I had an injection in my right upper quadrant of my leg of a similar drug of zofran(forgot the name) for anti nausea after waking up from surgery. This was over 3 weeks ago. About 1 day post recovery I had a constant numbing sensation near the injection site about 3-5 inches wide. 3 weeks has passed and the numbness is still constant with a little tenderness (pain) when pushed on. I just noticed when I got goosebumps today and I happened to look down at my leg and saw just in that same patch of numbness there were no raised goosebumps it was smooth, but surrounding the patch was covered in goosebumps. I m concerned there might be nerve or muscle damage?
