Hello, thank you for your question about Exparel being required for an arm lift and whether Exparel is worth the expense. In my opinion, you do NOT need Exparel for your arm lift, arm reduction, or brachioplasty. After an arm lift, you should NOT have that much pain. All my arm reduction patients are very well controlled with oral pain medication. I hope this information about Exparel and an armlift helps! Good luck with your arm lift. Sincerely, Dr. Katzen.
