However, speaking as a chiropractor with 10 years of experience, here's a very objective and hard-hitting fact:,<\/span><span class=\"\"> Your throbbing and swollen thumb isn't just a muscle ache,<\/span><span class=\"\"> This is because of \u2018tendinitis,\u2018 a condition where the \u2019tendons,' which are like ropes connecting bone and muscle, become frayed and

home care secret that perfectly replaces expensive protectors with a 1,000-won tape sold at pharmacies.<\/span><\/p>\n<h3 data-path-to-node=\"7\"><span class=\"\">The reason for burning under the

When you lift a heavy laptop or a child's torso with both hands,<\/span><span class=\"\"> Our wrists experience very harsh mechanical loads.<\/span><\/p>\n<p data-path-to-node=\"8\"><span

to the tip of the thumb.<\/span><span class=\"\"> These tendons pass through a very narrow and tight tunnel called a \u2018tendon sheath\u2019 at the wrist to prevent them from dislocating from the bone.<\/span><\/p>\n<p data-path-to-node=\"9\"><span class=\"\">The problem arises when you grip a heavy tablet tightly to avoid dropping it, or type incessantly.<\/span><span class=\"\"> Inside this narrow tunnel, tendons thousands of times a day,<\/span><span class=\"\"> It is repeatedly slipping tens of thousands of times, causing intense friction.<\/span><span class=\"\"> Friction can cause a hot inflammation and thickening of the sheath surrounding the tendon (tenosynovium).<\/span><span class=\"\"> The tunnel is still the same, but the rope passing through it has swollen up.,<\/span><span class=\"\"> 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.<\/span><span class=\"\"> This is \u2018De Quervain's Tenosynovitis\u2019, named after a Swiss doctor,<\/span><span class=\"\"> This is the frightening reality of smartphone thumb, also known as

data-path-to-node=\"14\"><span class=\"\">As I explained earlier in terms of anatomy,<\/span><span class=\"\"> Tenosynovitis is not a condition where muscles are stiff, but rather where the sheath of

class=\"\"> Inflammation worsens exponentially, and micro-tears in the tendons accelerate further.<\/span><span class=\"\"> You must never press or massage the wrist area painful due to tendinitis strongly, and,<\/span><span class=\"\"> The only correct answer is to unconditionally reduce physical friction and take a &#039;rest&#039;.<\/span><\/p>\n<h3 data-path-to-node=\"15\"><span
