nightnurse,
It might be worth finding a good women's health/hormone specialist to check you out. All hormones are regulated in the brain. A dysfunction could be causing other symptoms. Check out
https://www.womensinternational.com/..._referral.html for a good referral in your area. Your BC pills may be not right for you while you are still healing.
btw, I am a serious believer in women getting good hormone advice beyond the generic advice from most OB/GYN's. It changed my wife back into the woman I married 31 years ago. Bad hormones make for poor stress tolerance.
My best to you.
