1 month post-op: Right forearm SEVERE pain, numbness, worse on extension, surgeon acts puzzled, says is phlebitis?

This is a difficult issue to address over the internet. There are certainly nerves in the arm that can get trapped in scar tissue as your arms heal after an arm lift. This can be painful as you move your arm, since the nerve is stretched and irritated with the movement. Aggressive massage at the site of nerve pain is what I would recommend, and you could even consider ultrasound therapy by a physical or occupational therapist. With time, the scar tissue will soften, and your symptoms can improve or even resolve. Swelling in the arm, forearm and hand can be present for several weeks after an arm lift, and it may take three months to resolve. If the swelling is causing pain, a compression garment can help until your body heals and the swelling goes away.
