When your bicep is released, the long head is cut where it inserts into the shoulder so now, my bicep is only attached with the short head so instead of a bi cep, it’s now a mono cep. Before surgery, I was unable to raise my arm above my head without significant pain. Now, five years later, full range of motion without pain but a loss of strength and I have cramping on occasion which I do not expect to improve unless my bicep is surgically reattached. As with most things in life, it’s a trade off.
