I have started having pain and limited movement in my hand. Now it has started swelling on the back of my hand, and the skin is getting red and hot. It is much hotter than the other hand, as well. The fingers are not affected yet and I have had no injury to it. What could cause this?
Redness, swelling and heat all sound like there could be some kind of inflammation. You really should see your doctor to find out whether there is an infection or what else might be causing it. Some other things that might cause these are such serious conditions as arthritis, rheumatoid arthritis, and some kinds of nerve pain. If you are not suffering from some kind of infection, you might consider seeing an orthopedist to see if there's something wrong with the bones themselves. Best of luck to you!
