Has ThermiTight permanently scarred/damaged skin on my inner thighs from burns? (photos)

I had 10-15 blisters and hard ridges/burns on each thigh from very ThermiTight. The blisters have crusted over but I still have hard ridges (scars?) where probe touched my skin, and after 5 weeks, my thighs still feel lumpy and look a lot worse; my skin is still numb and bruised. Is this normal? I'm concerned that blisters and hard ridges are caused by the probe heating too quickly --it was painfully hot. Has ThermiTight permanently scarred and damaged my skin. Will this heal on its own?
