eeeeeeegad, I am so sorry that your weekend has been this bad....it could not help that you did not have us to keep you company.
Yes, I have been so bad off that I too wondered if i would even be able to get out of bed. I stumbled, and bounced of walls just to get to the bathroom...I was totally non-functional. And, when you live alone, it is especially scary. The last time this happened to me, I went to my rheumy and she gave me a medrol injection. This really helped and I have felt better ever since. I have also gotten cortisone shots in my hip when that pain was so bad.
My back pains run horizontally accross my back between the shoulder blades. Don't know what causes it, but it is the worst. I take Dilaudid for the pain, and can usually get some relief.
I also keep a walking cane close by when I am in bad flare. This just gives me a little support, and I feel safer when trying to walk.
I wish I could give you a hug, and be there to help you through this.
