Arm lift surgery. Would it be OK to travel to Florida for Thanksgiving the following week?

This is a good question for your plastic surgeon.  In my practice, I would be asking you questions such as: what are your planned It's activities in Florida? How long will you be gone? Best wishes for an outcome that you will be very pleased with.

Thank you for reaching out about the sharp nerve pain you're experiencing in your left forearm following a brachioplasty. Swelling is expected after an arm lift, and this swelling can sometimes compress the nerves, leading to pain. It's crucial to inform your plastic surgeon about this pain.
To alleviate swelling, I recommend:
Keep your elbows and wrists straight.
Elevating your hands above your heart.
Using compression garments.
By following these suggestions, the swelling and associated nerve pain should diminish. Always consult with your surgeon regarding any post-operative concerns.
Sincerely,
Dr. Katzen

Because of the dates associated with your question, I assume that my response would be OBE.  Hope everything worked out if you traveled, although I would not have recommended it.
