Thanks to everyone for the get well wishes.
Donna, I'm glad to hear your pain has gone away. I've heard that pilates is a wonderful form of exercise. Guess I should take it up when I'm able. By the way, Mort also has osteoporosis and takes Actonel. My youngest daughter does too.
Interesting note to this story....
I went to my regular Pilates class tonight, with the instructor is very knowledgeable about the body and how it works.
I told her the story of the medication and my pain, and she asked what the "normal" side effects should be. I told her "gastrointestinal".
She said, there you go, it was probably gas! She said sometimes gas can feel like a vise tightening, and that described the pain exactly.
What ever it was, it's completely gone now, and my back is just as strong as it was before I took that medication!
