A sharp nerve type pain in my left forearm after brachioplasty.

This could be normal or it could be an issue, but only your plastic surgeon can tell you after they examine your arms. My patients get occasional shooting pains and these go away about 3 to 4 weeks after surgery. Best wishes always, Dr. ALDO :)

Nerve discomfort in the forearm is fairly common after a brachioplasty due to nerve injury.  This may manifest as numbness, pain, dysesthesias, or tingling.  This type of thing usually resolves after a period of time, but not always.  You should discuss with your surgeon if it does not.

First off- please tell your surgeon so he or she can examine you to make sure everything is healing as expected.

That being said, it is not unusual to have such pains a few weeks after surgery as the nerves may be "coming back online" following the trauma of surgery.  Also, the skin may be hypersensitive for this same reason.  All sounds pretty normal to me. I find light compression to be effective in managing this.Good luck
