Hi adiben101 in Kirkland, WA, Thank you for your question regarding scars under the armpit after an arm lift. Thank you for your history. Based on your history, it appears you have contact dermatitis or an allergic reaction to the garment. I would contact your arm lift plastic surgeon immediately. Burning of this nature is not normal after an arm lift or, in fact, any other plastic surgery procedure. If you believe the burning and chafing are due to the garment, most plastic surgeons suggest that you discontinue the arm compression garment. Your arm skin needs to breathe. There are some other compression devices you can wear instead of the arm garments. These include ACE bandages. You may need to wear the ACE bandages for one to two weeks before using the arm compression garments again. You may also need topical creams or lotions applied to your arm toreducee chafing and burning. These are important things to discuss with your chosen arm lift plastic surgeon. You could also be allergic to the material in the arm garment. Alternatively, you may be allergic to the dressing or even the skin prep used during the arm lift procedure. Nonetheless, you must follow up with your brachioplasty plastic surgeon. Given the conditions you describe, it is best to follow up with your chosen plastic surgeon immediately. I hope this answers your questions regarding the arm reduction, specifically the scars under the armpit after an arm lift. If you have any further questions about arm lift, arm reduction, brachioplasty, arm scar revision, or arm crease fat grafting, contact an experienced plastic surgeon.

Since an arm lift can be a challenging surgery, please seek an experienced, board-certified plastic surgeon with significant experience performing these types of lifts. Do your research.

Carefully review their before-and-after photos and check their reviews on RealSelf.
