Glad your D&C went well and you're not in any real serious pain. Sorry to hear about the fever & scariness of it, you did just have some trauma to your body and you definitely need to REST, REST, REST take your tylenol or ibuprophen (which I think works better) to reduce any inflammation or pain.
Don't be too frightened.... I do want to say that don't put allot into the "discharge diagnosis" because it doesn't nessicarily mean you have endometriosis. They aren't obstitricians, kwim. Your OB's will be the ones to find that out especially since they just did a D&C on you they will have had a better look inside instead of what an ER doc's discharge diagnosis. (I've had an ER doc tell me this himself, they have to discharge with a diagnosis and recommend follow-up with PCP or OB)
Glad you came and updated, was wondering how things went.... glad you're safe and home now. Take it easy there honey!
