Hello. This is Infotherapy, prescribing healthy information.
I am a manual therapist with 10 years of experience, managing the joint health and pain of numerous patients in the field. When I consult with patients in my office who complain of wrist and finger pain due to tenosynovitis, You realize that the causes of your pain are deeply rooted in your daily life.
“Teacher, After work, lying in bed, gripping a hefty, pro-grade tablet with both hands, playing a visually stunning mobile game, or, I've been typing non-stop on my keyboard all weekend, writing web novels, and the bottom of my thumb feels like it's going to fall off.”Recently, I made up my mind and switched to a heavy, high-performance 16-inch laptop., My wrist has been throbbing ever since I twisted it while lifting and moving that with one hand.”My child, who is just around 20 months old, has suddenly become much heavier, My wrist feels like it's going to break when I lift her from the floor by getting my hands under her armpits and doing a flashy lift.“
playing action games for a long time while tightly gripping such a heavy smart device, and put my keyboard and mouse through a lot to write., To those who have to lift their growing, heavy child every day, first and foremost, And the most critically damaged joint is the ‘wrist connected to the thumb.'.
Many people simply think, “My muscles are just a bit stiff,” and then apply a patch or strongly massage the sore area with their opposite hand, leaving it untreated. However, speaking as a chiropractor with 10 years of experience, here's a very objective and hard-hitting fact:, Your throbbing and swollen thumb isn't just a muscle ache, This is because of ‘tendinitis,‘ a condition where the ’tendons,' which are like ropes connecting bone and muscle, become frayed and swollen.
Before relying on expensive wrist braces, A global self-diagnostic method to check in 1 second at home if your wrist pain is actually tenosynovitis, and, The worst habits that trigger inflammation, And we will thoroughly and generously explore the 0-won home care secret that perfectly replaces expensive protectors with a 1,000-won tape sold at pharmacies.
The reason for burning under the thumb
The anatomical truth of De Quervain's tenosynovitis: Our thumbs constantly move to touch smartphone screens, When you lift a heavy laptop or a child's torso with both hands, Our wrists experience very harsh mechanical loads.
The two strong tendons that abduct and extend the thumb outward and upward (abductor pollicis longus, The extensor pollicis longus muscle extends from the forearm to the tip of the thumb. These tendons pass through a very narrow and tight tunnel called a ‘tendon sheath’ at the wrist to prevent them from dislocating from the bone.
The problem arises when you grip a heavy tablet tightly to avoid dropping it, or type incessantly. Inside this narrow tunnel, tendons thousands of times a day, It is repeatedly slipping tens of thousands of times, causing intense friction. Friction can cause a hot inflammation and thickening of the sheath surrounding the tendon (tenosynovium). The tunnel is still the same, but the rope passing through it has swollen up., Even a slight movement of my thumb causes the rope to scrape against the tunnel wall, resulting in a sharp pain that feels like it could make tears spring to my eyes. This is ‘De Quervain's Tenosynovitis’, named after a Swiss doctor, This is the frightening reality of smartphone thumb, also known as mommy's thumb.
Real Wrist Tenosynovitis Self-Diagnosis in 1 Second (Finkelstein Test)
Is the throbbing in the lower part of my thumb just stiffness, Or, I will tell you about the ‘Finkelstein Test,’ the most reliable and globally recognized orthopedic diagnostic method that you can check yourself before going to the hospital to see if it's acute tenosynovitis that requires immediate discontinuation of use.
Step 1: Extend your injured arm straight forward., Hold your palm facing inward towards your torso (towards the opposite shoulder).
Step 2: Fold your thumb in deep towards your palm.
Step 3: Make a fist by tightly gripping your thumb with your other four fingers.
Step 4 (Core): With your fists clenched, Gently bend your wrist downward in the direction of your pinky finger.
Check results: The moment you bend your wrist down, “Ouch!" along the line from the base of the thumb to the wrist.” 소리가 날 정도로 날카롭고 끊어질 듯한 통증이 발생한다면 당신은 100% 드퀘르벵 건초염입니다. This is a serious inflammatory condition where even stretching can be harmful.
The worst thing you should never do
If the Finkelstein test was strongly positive (pain) with mercilessly massaging the affected area, Many people massage painful areas by pressing firmly or rubbing them vigorously with the fingers of their opposite hand in an attempt to relieve the pain. However, this is the worst act of self-harm, like pouring gasoline on a burning house.
As I explained earlier in terms of anatomy, Tenosynovitis is not a condition where muscles are stiff, but rather where the sheath of the tendon is eroded, torn, and swollen due to friction. What would happen if you vigorously rubbed a scraped knee that was bleeding and swollen with your hands? Inflammation worsens exponentially, and micro-tears in the tendons accelerate further. You must never press or massage the wrist area painful due to tendinitis strongly, and, The only correct answer is to unconditionally reduce physical friction and take a 'rest'.
The 1,000 Won Miracle That Prevents Surgery
Zero-cost home care using paper tape. Tendinitis heals only if you rest and don't use your hands, but, The reality is that office workers cannot stop typing, and parents cannot help but hug their children. At this time, before buying a thick and uncomfortable wrist brace costing tens of thousands of won, I will introduce a manual therapy-style 'taping fixation method' that dramatically reduces the load on tendons using just a 1,000-won apricot-colored paper tape (such as micropore tape) sold at pharmacies.
-
Width 2, easily available at pharmacies.Prepare a piece of paper medical tape about 5 cm long.
-
Starting from the first joint of the thumb (just below the fingernail), Cut the tape to a length that extends past the base of the thumb and up to 5 cm above the wrist.
-
With the thumb straight, Firmly attach the cut tape in a straight line from the tip of the thumb to the wrist. There is no need to pull the skin tightly; simply apply the tape so that it adheres closely without any bunching.
-
Cut another piece of tape of the same length, Apply it one more time by overlapping it on top of the first tape. (This is to double the support capacity.)
Therapist's Top Tips: This simple straight taping saves your wrist. Because overlapping paper tape is not elastic, It acts as an excellent brake when you unconsciously try to bend or twist your thumb excessively. While not feeling stuffy like a thick protective pad or interfering with mouse typing, It drastically reduces the area of friction where tendons scrape as they pass through a narrow tunnel by more than half, allowing inflammation to gradually subside even while going about daily life.
heavy smart devices, Flashy mobile games, And the daily routine of holding a beloved child. Behind all these happy and essential activities, your fragile wrist tendons are silently screaming. If your wrist aches and your thumb throbs, Do not rub it indiscriminately or cover it with a patch.
Clearly identify your condition with the 1-second self-diagnosis I shared today, and, For the time being, we recommend using heavy tablets on a stand. And please stop by a pharmacy and put a sturdy cast on my thumb with just a 1,000-won roll of tape. This single, small, thin strip of tape will be the best shield against expensive extracorporeal shockwave therapy costs and terrible surgery. Until the day you regain a light daily life without the tingling sensation in your wrist, Infotherapy will always protect your joints with objective and realistic solutions.
