Will a surgeon operate on someone that already had surgery done five months prior for the same problem? ( hand surgery )

Depends: It depends on the serious nature of the problem, possible known complications, patient need/ medical history, etc. Has it happened before, yes but every case is relatively different. Hope this helps, please be more specific if you can. Thanks!

Possibly but: Will need all the records and x-rays so the surgeon has the proper tools to evaluate you. And of course it really depends what the condition is.

Yes, if warranted: The need for revision sometimes occurs and it's not uncommon to have a 2 stage procedure in the hand. It does depend on your diagnosis however.
