Omeprazole and blood tests

I've been taking Prilosec since late 2003 and it hasn't been until now that I've linked all the strange symptoms I've been having to taking Prilosec. I've been having anxiety, heart pulps, strange, stabbing headaches that come and go in a flash, occasional sensitivity to light, pain behind the eye, dizziness, fogginess, and fatigue. I've been to the doctor several times over the past few years hoping to find a cause. After many blood tests, x-rays, heart tests, etc, he couldn't find anything and just said anxiety and that I should try yoga. It surprises me that he wouldn't even suggest that I try coming off the Prilosec to see if that could do it since it appears that many people experience these strange symptoms.

I've stopped taking Prilosec today and I'm hopeful that all of this will clear up and I can get back to normal.

After taking it for 6 days, Omeprazole caused me to suffer arthralgia. That translates to joint pain (knees, elbows, wrists, shoulders, neck, back), swelling (hands and feet), stiffness (all over), weakness (especially in the hands), and fatigue. I am having problems driving because it hurts to hold the steering wheel and exert enough pressure to turn the wheel, and overall I can barely move. I found a case study on the net that examined five other people who also got arthralgia, and the symptoms went away 10-18 days after stopping the drug. This is only my first day off Omeprazole, so I hope things will clear up for me quickly.

My husband was on Prilosec for several years, and switched to Omeprazole by our prescription plan. I don't know if the medication is the cause, but he started experiencing chest pain, and occasional shortness of breath, not the same as the acid reflux discomfort. He went to the Dr. and was tested by blood tests, EKG and chest x-ray. All were normal, so stress thallium test was ordered. He passed the stress test with no problem, but had a small abnormality on the thallium scan. He was referred to a cardiologist because of this and a heart cath was performed, also normal so thallium scan was a false positive. The cardiologist changed his medication to Nexium. Could this all be due to switching to Omeprazole? I don't know, but the timing is suspicious.
