Treatments for chronic pain, I can't stand this anymore. 8 years post op trim method labiaplasty. What can I do?

Pain following labiaplasty is uncommon and can occur following both the wedge or trim technique. Typically pain occurs when tissues are placed under tension. Recommended reatments depend on what your examination is like.
PRP injections work very well in some situations, but surgical correction may be necessary.

Thank you for your questionI believe that the treatment parameters for your problem can only be determined with a careful examinations they will depend on the specific locations, positioning and types of scars. My recommendation is to do an extensive search for surgeons who are experienced at correcting botched labiaplasties, do in person consultions, review their work and compare what they say.It would be inappropriate to give recommendations without seeing the specific issues.

Im sorry you are having issue post labiaplasty procedure. Please consult a labiaplasty revision specialist to discuss your options. Be sure to choose a board-certified plastic surgeon that specializes in this procedure and is well known for their work.
