Omeprazole and weakness

I've been on Prilosec for 3 yrs, and most recently put on Zegerid, which is omeprazole/sodium bicarbonate. I have had on both the occasional chest pain, anxiety, joint pains, and weakness/fatigue, and mild depression/with aggitation, and confusion. I am on 40 mg a day. These side effects are real, no doubt about it.

This drug caused a week from hell for me. It started out with severe back pain and leg pain and weakness on my right side. Soon, the pain spread all over my back, into my shoulders, and down my right arm. My balance was so bad I could not walk from one side of the room to the other. TMJ was worse, I felt like my teeth were moving. I had such bad fatigue, I would just lay in bed. Plus, my mouth was so dry. It took me about 5 days to get rid of the side effects after I stopped the drug.

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.

Omeprazole was successful in relieving excess stomach acid but unfortunately some severe unwanted side effects were developing after the first two weeks of administration.

The most prominent side effect was constriction and tenderness in the chest cavity which was affecting breathing ability at the height of these episodes. A second side effect was the gradually increasing levels of numbness and tingling sensations on the left side of my body in the arm and leg. A third effect was progressively increasing weakness developing in my legs which at times caused tremors and shakyness which affected my endurance during activity levels.
