Silicon symptoms and conditions

I started Prednisone 2 weeks ago and gradually started having leg cramps. They have gotten worse over the last couple of days. They are in my ankles and feet and I have to get up several times a night just to sit until they relax. We plan to decrease the dosage in two weeks, but this is most annoying. Of course, it's far better than what I was experiencing with pain and sleepless nights and had gotten so I could barely move. My hands were swollen and tight, my arms ached with every move and movements were very limited. My bones in my feet felt (and sounded) as though they were shifting around when I got up to walk. My knees were weak. I was just diagnosed with polymyalgia rheumatica. I feel 70-80% improved. Just wondered if anyone else has had these symptoms on Prednisone. It didn't do this with the dosepaks.

I took kenalog when i was very young for allergies. I was not told of side effects. I noticed a dimple and asked a new nurse about it. She said it was from the kenalog and showed me her butt where half of it and sunk in and had to be injected with silicon to fill it back out. I was horrified--the first nurse was giving it to me in my skinny little arm. Also I now wonder if that time in college where I was on and off my period every 2 weeks was from the shots. I had to start taking birth control to regulate them.
