In March, my pharmacy changed brands on my lithium and the absorption tanked sending me into crisis. We found the 1 pharm using the better brand, increased the dose and switched, Now Celebrex is tearing up my stomach. Dr isn't sure but thinks it might be tied to the lith. We stopped that, which reduced stomach issues but now I hurt. I'm back to needing a cane for my knees which strains my bad shoulder. 35 years of comp work ruined hands/wrist. Tired of pain.
