I am very glad I found this site. I have been taking Prilosec OTC for 3 years now and it took care of my acid reflux. I woke up 6 months ago feeling like my "funny bone" got hit but never subsided. I then learned it was possibly my ulna nerve. Burning sensation in my left pinky finger and half my ring finger. Anyone experienced this? I switched to a generic Omeprazole at Walgreens a couple of weeks ago and I have experienced the most excruciating sharp, shooting pain in my neck, shoulders and lower back and sometimes other joint areas. Anyone experience this with the generic brand? I am going off of it and see what happens. The pain is intense!!! Thanks for this site!
