I’m facing severe nerve pain in my left wrist is this normal in postpartum I had c sec 3months back

A. I don't think there could be any connection between your left wrist pain and section. If the pain was in the area where you got cut during c section then it could be due to a nerve damage during the surgery or an improperly healing nerve. But wrist pain could be a totally different thing. It's best to consult with your doctor if the pain persists for a longer period.
