Yes I have this hard knot ontop of my right hand and I ve noticed that its getting bigger and it feels like it is on my vein, and if i accidently hit it .its painful, sometimes I get a tingling feeling in , my fingers, I wear a hand brace when it goes to hurting and that helps the pain.
Hi, From history it seems that you might be having wrist ganglion giving this trouble. This is a common condition.If you require go for removal of ganglion. Consult surgeon and get examined. Ok and take care.
