Hi. I have itchy burning sensation on my palms, mostly near my joints. What could be the cause? How can I make it stop?

Carpal tunnel. It could be carpal tunnel syndrome, caused by compression of the nerves in the wrists. It could also be a contact or irritant reaction to something you applied to your hands. There are some internal diseases that can cause it too, but that is less common. Your doctor should be able to tell you if it's carpal tunnel, or refer you to an orthopedist.
