Not to scare you, but the only way to know for sure that you have endometriosis is to het a surgery. This should help with the nausea.
To get back to your orginal post, thank you so much for the help. I will have to try it.
Yes, parsley has some useful properties, but the strong anti-inflammatory you were on may have helped too. Endo is easily diagnosed once the doctor gets a look inside, during a surgery. Some OB/GYNs will diagnose it without performing a surgery, just based on a process of elimination. I hope you don't have endo, and am glad to hear your symptoms have resolved.
