Can laser Liposuction cause permanent muscle and/or nerve damage?

I had laser lipo suction at sono bello four weeks ago I am still experiencing numbness pain and itching and hard lumps and bumps. I have very sensitive skin, and I am wondering if this is part of the healing process or if I may be having a reaction to the numbing solution that was used. The surgeon does not know why the itching he told me to use antihistamines such as Benadryl tablets and ornament neither of which has helped at all. Is this all part of the healing process. Please help me.
