Severe Symptoms of Stroke, MS, Heart Attack, Panic Attack.....

I have had GERD for many years, and have taken prilosec off and on when my symptoms worsen. About a month ago, I took it for two weeks, and have since been through a total nightmare with my health. I have been in and out of the ER with symptoms of a stroke, MS, heart attack, panic attack, ringing ears, freezing hands and feet, muscle cramps and twitching, weakness, tingling, numbness, and left sided partial paralysis including half of my face. I have felt on the brink of death many days and nights. I don't have health insurance, and have had to pay out of pocket for CT scans, MRI's, an ambulance trip, blood work, seeing three specialists, EKG's and on and on... So far, my tests aren't revealing the problem. The only test I haven't had is an MRI with contrast to look at the vascular system of my brain. This has ruined my quality of life completely. I am a total wreck, and terrified. I feel so ill. Is this medicine poison or what???
