Is BBL safe for patients with current back problems such as sciatic nerve, herniated disc, etc.?

As far as safety of the operation is concerned, I believe that yes, providing that positioning during surgery will not have an affect on your herniated disc. 

hello thank you for your question and provided information as well..based on your question, the ideal is to be evaluated by your basic doctor who interconstructs you with orthopedics so that you can see and evaluate your case, if you give authorization you can be consulted with a certified plastic surgeon.
