Concern about permanent scar tissue formation in both underarms following MiraDry treatment 18 months on. Can it be treated?

I had my first MiraDry 21m ago on Lv 2. My second treatment 3m later was performed on Lv 4 as the first was not very successful. Both were done by the clinic nurse. 18 months on there is still a residual lumpy appearance with suspected scar tissue or fibrous band formation in both underarms from damage to the underlying tissue. The area was massaged regularly. Have you seen this in your experience & can you recommend a therapy to help treat the damaged tissue? Most of the sweating has returned.
