has anyone else ever had trouble with muscle spams in your pelvic area?

I saw my ob today and told her how bad my cramping gets before/after my periods and during sex. she seems to think it's muscle spasms due to my c section not healing fully. which my son is over two years old. she says that I can still have that and that's what is causing this pain and wants me to do physical therapy for the next month for the pelvic pain..

has this ever happened to anyone else? I just feel like there is much more to my issue.
