Why is Ultrasonic Cavitation contraindicated for persons with HIV?

Hello, I'm a 48 year old HIV+ woman and for years I've been extremely subconscious about the cellulite on my thighs and buttocks. I've heard of ultrasonic cavitation and surgery scares me. However, I've heard about the contraindications for autoimmune diseases. I've researched this often and I've been unable to locate a concise answer. I'm currently on my HIV medications and I'm fully treatment adherent. Is it possible for me to have this procedure done at all? Thanks for the response.
