<s>[INST] For months (3-6) I have had a small round bump on the top of my hand. Not bruning, itching...nothing...just a small pimple like bump. Finally I started pick at it and it did get smaller...however now there is a tiny pin-prick of a hole in the center...but still a small red bump.  tried to freeze it off but it did nothing. (thinking it was a wart) [/INST] Thanks for writing to HCM.As your symptoms suggest it is likely to be a ganglion. But it does need a physical examination for reaching an appropriate diagnosis and thence necessary treatment. So it is advisable that you visit a general surgeon. </s>
