Miradry lumps and red marks. Is this normal?

So happy to answer this question. Everything in life has risks,
even MiraDry. I suspect your symptoms are caused by the connective tissue in your body which creates the feeling of tightness and lumpiness. This is usually temporary and resolves over time.
With MiraDry, the device is designed to allow the energy to go as far
as the layer where the glands live and does work on water bearing
structures. 
Follow up with your treating doctor and discuss this issue. Perhaps an injection of PRP might help!

You may experience some
swelling, minor bruising and tenderness of the underarms, which should subside
within a couple of weeks. We recommend avoiding strenuous activity requiring
your arms until your symptoms have resolved.This can take 4-8 weeks to resolve but see your doctor for follow up

Your problems are not common but can be assessed during an examination. We have found the Miradry to be extremely safe and effective. Best, Dr. Karamanoukian Los Angeles
