I had a severe R.A. flare up in my right shoulder last Friday, and couldn't even lift my right arm for 2 days. I usually don't take any type of pharmaceuticals/prescription meds (Vitamins & natural supplements & IPF), but this was bad enough that I had to take a 5 day prednisone pack. The problem with that is whenever I have to take prednisone, it prevents me from being able to sleep, so Friday-Sunday night, I got a total of maybe 4 hours sleep combined. Last night was the first night since Friday that I got at least 4 hours sleep, and got my shoulder back to about 80% now..... Not a fun weekend.....
