Description : What can cause tendonitis? My hand has been pitying mercilessly for days, so I went to the doctor and found out I had tendonitis. He didn't really say almost anything else. The interesting thing is, I didn’t get hit anywhere, and I didn’t even pull or jerk my hand. So what could it be?
Last Answer : Tendonitis is not because someone hits their hand or jerks it. It usually occurs when you perform the same series of movements over a long period of time, such as while working, and thereby continuously load ... often from the way they use scissors, but even using a cell phone can be a problem.
