Can Velashape Cause Permanent Damage?

I had two treatments and cancelled further ones. The pain was unbearable and the bruising significant. Question: can this cause unreparable damage? In specific, for my inner thigh on left, which was very smooth already, the bruising was huge and is still lightly visible after 3 weeks. The smooth area now actually has a couple bumps protruding. So I went from smooth (pretreatment) to bumpy (after two treatments). Should I see an MD to confirm no permanent damage has been done?
