\"10\ub144Hello.<\/span> This is Infotherapy, prescribing healthy information.<\/span><\/p>\n

I am a manual therapist with 10 years of experience, managing the joint health and pain of numerous patients in the field.<\/span> When I consult with patients who come into the examination room holding their elbow in pain, with a pained expression,<\/span> One hundred out of a hundred times, they say this as if they've been wronged.<\/span> \u201cTeacher,<\/span> I've never even seen a tennis racket in my life, but when I went to the hospital, they said I have tennis elbow.<\/span> Even lifting a glass of water, my hand trembles from lack of strength,<\/span> It hurts like a needle is stabbing my elbow when I turn the doorknob, and it's killing me.<\/span>\u201c<\/span><\/p>\n

The name \"tennis elbow\" makes it easy to mistake it for a sports injury, but,<\/span> In reality, over 95% of the people who come to me for this disease are living ordinary lives.<\/span> Office worker who types on a keyboard and mouse all day without rest,<\/span> For those who work, and then grip their heavy mechanical keyboards and mice to intensely enjoy PC games,<\/span> And above all, the elbows of parents, who have to lift their child, weighing close to 13-15 kg, dozens of times a day from the floor, will be the first to suffer.,<\/span> and it crumbles most miserably.<\/span><\/p>\n

When many people's elbows ache and throb, they strongly press and massage the painful spot where a bone protrudes with their opposite hand, or,<\/span> You go to the hospital and get a steroid shot, commonly known as a \u2018bone shot,' to numb the pain.<\/span> However, speaking as a chiropractor with 10 years of experience, here's a very objective and hard-hitting fact:,<\/span> Your elbow is not just sore from muscle strain; it is in a state of \u2018rupture\u2019 where the rope (tendon) connecting your bone and muscle has micro-tears and fraying from enduring tens of thousands of frictions.<\/span><\/p>\n

Before relying on expensive elbow braces or injections that come with side effects,<\/span> A 1-second self-diagnosis method to identify the real cause of your elbow pain, and,<\/span> Worst things that trigger inflammation,<\/span> And we will thoroughly and in detail uncover the miraculous zero-cost home care secret in chiropractic therapy that rebuilds weakened tendons as strong as steel with just a \u2018yellow rubber band\u2018 rolling around in a drawer and an \u2019empty water bottle.\".<\/span><\/p>\n

Why is the outside of my elbow burning?<\/span><\/h3>\n

The anatomical truth of tennis elbow (lateral epicondylitis). When we lift our fingers to type on a keyboard,<\/span> Grasp the mouse and bend your wrist back,<\/span> When lifting a heavy child from the floor by their armpits, an immense mechanical load is placed on our forearms.<\/span><\/p>\n

The muscles that lift the wrist and fingers toward the back of the hand are called \u2018extensors'.,<\/span> These muscles split into several branches, run up the forearm, and eventually bundle together into a single rope (tendon) that firmly attaches to the bony bump on the outside of the elbow (lateral epicondyle).<\/span> The problem occurs when the wrist is overused beyond the limit that this rope can handle.<\/span><\/p>\n

Lifting heavy objects or typing for extended periods with wrists bent can cause,<\/span> This tendon experiences constant micro-tears at its attachment point to the bone.<\/span> our body tries to heal this wound while we sleep, but,<\/span> Without any time to recover, the next day I'm once again holding a mouse, lifting my child, and reinjuring myself.<\/span> Eventually, the collagen fibers in the tendon, which were once normal and elastic, become tangled and worn out,<\/span> This causes degenerative changes, which is the medical term \u2018Lateral Epicondylitis\u2019.,<\/span> That is, the terrifying reality of tennis elbow.<\/span> Its name is inflammation (-itis), but,<\/span> Once it enters the chronic phase, it becomes a severe condition called \u2018tendinosis\u2019 where inflammatory cells disappear and the tendon itself degenerates into a dry, rotten state, making it impossible to heal with ordinary anti-inflammatory drugs or rest alone.<\/span><\/p>\n

Real Tennis Elbow Self-Diagnosis in 1 Second (Cozen's Test) <\/span><\/h3>\n

Is the pain in my elbow right now just a minor muscle strain, or,<\/span> Or, we'll tell you about the \u2018Cozen's Test,\u2019 the most reliable orthopedic diagnostic method you can check yourself before going to the hospital, to see if you have tennis elbow, which requires immediate reduction in wrist use.<\/span><\/p>\n

Step 1:<\/span> Extend your affected arm straight forward and gently make a fist.<\/span> Turn your palm to face the sky.<\/span><\/p>\n

Step 2:<\/span> Clench your fist and strongly bend your wrist upwards towards the sky.<\/span><\/p>\n

Step 3 (Helper Required):<\/span> With your other hand or someone else's hand,<\/span> Punch clenched fist upwards and then press down firmly.<\/span> At the same time, the sore arm resists by holding up and exerting force.<\/span> Check results:<\/span> When resisting the downward force of a fist by pushing upwards,<\/span> Ouch!<\/span>\u201dIf you experience sharp pain so intense that it makes a sound, or if your arm suddenly loses all strength,<\/span> You have% 100 tennis elbow (tendon rupture) condition.<\/span><\/p>\n

The worst thing you should never do<\/span><\/h3>\n

If diagnosed with bone injections and bone massage for tennis elbow, the most common question patients ask is,<\/span> But there are two worst things you should never do.<\/span><\/p>\n

The first is to strongly rub or knead the sore elbow bone area with your fingers.<\/span> As explained before, this is a wound with torn and frayed tendons.<\/span> What will happen if you scratch and rub a severely scraped knee with bleeding and oozing wounds with your fingernails?<\/span> Temporary pain might lead to numbness, but a tendon rupture will further accelerate and become irreversible.<\/span> You should never massage a painful bone area directly,<\/span> If you want to relieve tension, you should gently work only the thick muscle part (muscle belly) on the lower forearm, 5-10 cm away from the bone.<\/span><\/p>\n

The second is frequent steroid injections (bone injections).<\/span> Steroids have a powerful anti-inflammatory effect, so the pain disappears as if by magic immediately after injection.<\/span> The patient mistakenly believes they are fully recovered and overexerts their wrist by lifting heavy objects.<\/span> However, only the pain is not felt, and the tendons continue to tear.,<\/span> Steroids themselves inhibit collagen production in tendons in the long term, leading to the fatal side effect of tendons being thinned and \u2018melted\u2019 like tissue paper.<\/span> Eventually, when the effect of the injection wears off, you will end up on the operating table with pain several times worse than before.<\/span><\/p>\n

Miraculous 0 Won Home Care That Prevents Surgery<\/span><\/h3>\n

The only scientific way to regenerate tendons that have become weakened back to steel-like toughness is through: yellow rubber bands and a water bottle.,<\/span> It's not about expensive braces, but about \u2018eccentric contraction\u2019 exercises that apply proper tension to the tendons, realigning collagen fibers in the correct direction.<\/span> Here are two of the best osteopathic physical therapy exercises you can do at home for free.<\/span><\/p>\n

Method 1.<\/span> Drawer \u2018Yellow Rubber Band\u2019 Finger Spreading Exercise (Isometric\/Early Rehabilitation) This exercise provides safe stimulation to the tendons when initial pain is severe.<\/span><\/p>\n

    \n
  1. \n

    Prepare a common, tough yellow rubber band that comes with food delivery.<\/span><\/p>\n<\/li>\n

  2. \n

    For the injured hand, bring the five fingers together and put a rubber band around them.<\/span> Around the fingernail<\/span><\/p>\n<\/li>\n

  3. \n

    Stretch the rubber band taut, overcoming its resistance by spreading your fingers wide.<\/span><\/p>\n<\/li>\n

  4. \n

    Hold this position for 5 seconds, then slowly contract.<\/span> Repeat this process 15 times for 3 sets.<\/span> to provide healthy stimulation to the entire extensor muscle of the fingers,<\/span> This is an excellent rehabilitation exercise that distributes the load concentrated on the elbow to the muscles of the entire hand and forearm.<\/span><\/p>\n<\/li>\n<\/ol>\n

    Method 2.<\/span> \u2018Empty Water Bottle\u2019 Eccentric Lowering (Eccentric Contraction \/ Core Rehab) This is the eccentric contraction exercise, known as the \"flower\" of tennis elbow rehabilitation.<\/span><\/p>\n

      \n
    1. \n

      Prepare a 500ml bottle of water.<\/span> First, fill the water halfway,<\/span> Once I adapt, I will fill it completely.<\/span>)<\/span><\/p>\n<\/li>\n

    2. \n

      Place your affected forearm on the edge of a desk or dining table,<\/span> I stick only my wrist out of the desk into the air.<\/span> Grasp the water bottle with the back of your hand facing the sky.<\/span><\/p>\n<\/li>\n

    3. \n

      (Key point) It's absolutely not about lifting a water bottle with the strength of your sore arm!<\/span> \u2018Using your non-injured hand, bend your wrist holding the water bottle upwards toward the sky.<\/span><\/p>\n<\/li>\n

    4. \n

      Take your other hand off.,<\/span> Now, holding the weight of the water bottle with only your injured arm, very slowly over 5 seconds,<\/span> Even if you're trembling, slowly lower your wrist as much as possible.<\/span><\/p>\n<\/li>\n

    5. \n

      Raise it to the opposite hand again.,<\/span> With an aching hand, hold slowly and lower for 15 repetitions, 3 sets.<\/span><\/p>\n<\/li>\n<\/ol>\n

      Therapist's Top Tips:<\/span> This \u2018holding and lowering motion,' where muscles lengthen while exerting force, is eccentric contraction.<\/span> When you perform this action, the collagen cells in your tangled tendons rearrange themselves neatly in a straight line, up and down, causing the tendons themselves to regenerate thicker and stronger.<\/span> It may be accompanied by slight stiffness,<\/span> If it's tolerable, you must persist consistently for the tendons to recover.<\/span><\/p>\n

      Heavy mouse and mechanical keyboard,<\/span> And the beloved child, who grows heavier every day.<\/span> Your elbow tendons were silently tearing and screaming as you bore the brunt of all this daily life.<\/span> If your elbow aches so much that you're afraid to even lift a cup of water,<\/span> Don't immediately rub or cover your aching bone with a patch.<\/span><\/p>\n

      Today, precisely assess your condition with the CoGen test that was explained.,<\/span> When lifting heavy objects, you need to immediately change your habit to gripping with your palms facing up (underhand grip) so that the back of your hands do not face the sky.<\/span> Then, after work, try investing just 10 minutes in a rehabilitation exercise: sit at your desk, hold a bottle of water, and slowly lower your wrist.<\/span> This small, slow movement revives frayed tendons like steel,<\/span> It will be the best prescription to save you from the horror of a terrible surgery.<\/span> Until the day you regain a light everyday life where you can effortlessly hold your child without pain.,<\/span> Infurtherapy will always protect your joints with objective and accurate answers.<\/span><\/p>\n
