After Two Emergency Room Visits And Three Weeks, I Still

After two emergency room visits and three weeks, I still have headcaches, stomach cramps, and cannot stand over 3 minutes without cramps in my legs. My wife thinks the pork we ate 24 hours prior might be problem, but Doctors are not sure. Initially, I had a headache all next day, then at bedtime, extreme neck & shoulder pain radiating down arms & legs. Still symptoms of stomach ache & not being able to stand.

Thanks, Don K
