Over lunch, I decided to read the Patient Education material that came with my PredniSONE 5 MG. Turns out possible side effects include bone problems and I am to make sure I have enough calcium and vitamin D in my diet while I’m taking this medicine. I believe therein lies a clue to my osteoporosis. For many years, I took an awful lot of this stuff; orally, injected and I.V. I’ll add another Vitamin D capsule to my routine while I’m on this stuff. I can’t afford to lose any more bone density! On the way to daycare, Daisy ate the banana out of my lunch bag. Occular Migraine. My second recently.
