Hi. Last Friday I had a bit of a stomach flu throwing up and watery diarreah all day, saturday felt a little better, went out had a few drinks, kept everything down...however started having a pain in my neck to very upper back when I was gettin ready which started on saturday...i have ahd this pain before due to whiplast last february, and an incident doing headstands and kidn of tworking my neck, but along with the other symptoms i got worried. As of MOnday I still have the sore neck upper back, and my head feels heavyalmost light headed but not, feels like a tension headache at the base of my skull and like someone has their hand on my head and squeezes off and on not very painful just a weird sensation...I worry constantly and my mind has crossed everywhere from brain tumors, to meningitis...I hav never had this sensation before, and reading online scares me more...any thing you may knwo on it would be greatly appreciated.
