Omeprazole and adverse reaction

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.
