My doctor put me on Fosamax immediately after my big 'back' incident with the bulging discs and the compression fracture. He and another doctor disagreed about me having osteoporosis, but they both said to take the drug.
I took Fosamax for a year, had horrible side effects (which I didn't know were from the Fosamax because of the horrible back pains and things)and finally quit them on my own. I felt amazingly better after a few weeks off the pills. Guess I'm one of the unlucky ones who gets all the bad effects.
I think my docs were just trying the preventative method because of that 'fracture', which I know happened almost 20 years previous to the bulging discs but no one would listen to me.
If you actually have or are tending towards the osteoporosis and can find a drug which doesn't cause you debilitating side effects, I'd for sure recommend it. Depending on age, the bones don't heal as fast as we get older.
I had a follow-up bone scan test last year and they found NO osteoporosis. Go figure. Never had it, took the drugs, still don't have it.
