There is an amazing Endometriosis support group called "Nancy's Nook". They help to match people with the best endo-knowledgeable OBGYNs in the nation!
What part of South Carolina? If you are close to Rock Hill, Please check Rock Hill OBGYN, They have a handful of wonderful Doctors, Myself personally love Dr. McClelland, He took care of me for many years until I moved out of state.
