I have developed bumps on my head, something like hive I suppose. I did find that taking one medication [Omeprazole caps] twice daily may have been the cause. On the instructions hives was listed as a side effect. So I quit taking them and the bumps almost went away. I started again one a day. Today I started getting the bumps again, they are itchy. I do have dry skin & hair. I have RA, take the meds for reflux and ulcer. Is it possible this medication has caused this for sure or could it be something else?
