Armpits are irritated after brachioplasty

Thank you for questions regarding irritated armpits after your arm lift or brachioplasty. Swelling after a brachioplasty is expected. It is very important that you wear your compression garment to minimize swelling, to protect the incision, and to help flatten the arm scar. Having only one picture and not a physical examination, it is impossible to tell if you need a larger arm garment. However, I would probably agree with your plastic surgeon that you do not need a larger garment. You need to continue to wear your present arm compression garment. I would not suggest you take a break from your compression garment. If you do so, this will only lead to more arm swelling. Thank you for your question regarding irritated armpits after your brachioplasty. If you have any more questions regarding post-operative care after an arm lift or brachioplasty, please contact my office. If you are looking for an arm lift or arm lift revision, please seek an experienced, board-certified plastic surgeon who has performed hundreds of arm lifts. Travel out-of-state if you need to seek such an arm lift expert. I hope that I've answered your questions regarding post-operative care after an arm lift.
Sincerely, Dr, Katzen.

Compression is important but it should never cause pain or irritation. Sometimes you can open the upper portion so it doesn't rub, etc.Check with your plastic surgeon for better options.

Hello dear!!
Thanks for the question and provided information as well. 
Without pictures it is hard to give you a recommendation. Remember that you are still early on healing process, and that it depends on each patient, most of the time is between 6 months and one year to see the final results. 
I suggest you to make an appointment with a board plastic surgeon for a good evaluation and to talk about your goals.
Good luck :)
