Post op care of decompression surgery of lateral femoral cutaneous nerve. I have this surgery wednesday, can you tell me the post op care please?

Call your surgeon. Call your surgeon today if you have a question. Even if its not during normal work hours, someone will be covering. In general, wounds should be kept dry until they are not oozing fluid, then it is ok to shower - usually 24-48 hours. Activity as tolerated. Obviously it depends on the incision location regarding any special instructions. Hope this helps.
