Is there harm in getting the second treatment if you still have tenderness in the arm area?

Congratulations on getting 80 to 85 % reduction in your sweating. The second treatment should be done at level 5 at three months from the first treatments. It sounds from your description like you're not fully recovered yet and you need to wait about 1 more month.Best wishes, Dr. Aldo

Miradry’s protocol recommends waiting 3 months before undergoing a second treatment. Waiting ensures that you have fully recovered from your previous treatment. Occasionally numbness/tingling occurs following a treatment. This typically resolves without any long term issues. But please check with your provider if your symptoms are normal/expected to make sure. This only can determined during a physical exam. We complete second treatment in most of our patients with very high if not 100% success rate

MiraDry is a wonderful procedure for patients with excessive sweating and underarm odor.  In my practice, I have found that patients with severe sweating may require a second treatment.  Most patients have 50% reduction in sweat and odor after the first treatment, and another 30% reduction in a 2nd treatment.  I recommend a second treatment no sooner than 6 months after the first treatment.  I would definitely not have a treatment if you still have numbness or sensitivity to the area as that indicates you still have some inflammation.  Good Luck!
