Hello Whatx2.
I am so sorry about your constant headache and constant pain. In this days I am constant pain too, and a very weird headache and constant internal spasms like if It were some force stretching my stomach and bowel. I understand you very well.
One question: when you go to ER, did they do you a blood analysis, was the result ok?.
When I go to ER and my blood work is ok, they send me to my home with tylenol :(
