Thank you for that mrsD. I'll do some more reading.

That last bit's rather scary though where you mentioned that the bisphosphonates are causing exactly what they are supposed to prevent.

I was on Actonel for a very short time but even with all my fractures, I never wanted to start taking it in the first place. The side effects were just too many, and too serious and I must admit I'm rather pleased to be off the medication now.
