Electric-like Pain Under Arm After Breast Lift and Aug.

It sounds like you're experiencing nerve regeneration, which is causing this feeling. It will eventually resolve itself as you recover from surgery

It is not unusual to have electricity like shooting sensations in the breast and particularly in the nipple after breast surgery. This is caused by stretching of the nerves that gives sensation to the breast which come out throughout the ribs. As time passes, and swelling subsides, these electric like pains should subside and gradually go away completely.

You had quite extensive surgery which required multiple hours to perform. One of he major risks to consider given your symptoms and history would be a pulmonary embolism which is a serious problem. There are other much less serious causes of your symptoms including muscle pain and spasm, nerve injury and even a hematoma.

Given the possibility of a pulmonary embolus, you should contact your surgeon immediately. He/she may want to see you immediately and better assess the situation.
