<s>[INST] I have a swelling which occurs on my back side of my right hand palm and tends to bend it inwards but when i take prednisone and diclofenac it subsides and after many days comes again. What is it Doctor? What other medicines do you suggest for me apart from the ones i use since they erode my stomach? [/INST] Hello, Looking at your details it looks that you may be suffering from tenosynovitis of extensor tendons at back of hand. This needs to be evaluated to know about the cause behind it. You should consult to your orthopedic doctor or a rheumatologist for this. You should get evaluation for connective tissue disorder and rheumatoid profile. Hope I have answered your question. Let me know if I can assist you further.  </s>
