Thank you for your question regarding right arm paralysis after an arm lift/brachioplasty. It would be best if you stuck with your plastic surgeon. Their advice is precious. In addition, I would consider consulting with a neurologist to determine precisely where the nerve is pinched. Usually, once the swelling subsides, the pressure on the nerve will also dissipate. The timeline is highly variable. It can take several weeks, but it will likely take 4-6 months to complete the healing. Again, I suggest you stick with your plastic surgeon and use their advice. You may want to consider consulting with a neurologist. Physical therapy may also be essential to optimize healing. Your plastic surgeon may also want to consider medication to help decrease the swelling, including steroids. Thank you for your question regarding right arm paralysis after an arm lift/brachioplasty.
