What should I do about painful scar tissue from c section?

Need more info... I am always apprehensive when i hear the words "scar tissue" and "pain" in the same sentence. Adhesions are a very common by-product of abdominal and pelvic surery and usually cause no symptoms whatsoever. Furthermore, they can only be seen surgically: not on physical exam, not by x-rays or u/s. I advise you to see your ob/gyne or primary care doctor to help sort out the cause of your pain.
See pain doc. See a board certified interventional pain physician that has access to cryolysis - works the best.
