Hi @detc, I am sorry you have osteoporosis. I was surprised by my diagnosis as I was a regular exerciser until an autoimmune disorder curtailed my activities. There is a history of osteoporosis in my family, I was pretty casual about talking calcium, and I drank wine regularly when I was younger. My aunt started getting spinal fractures and died shortly thereafter. She was in a lot of pain.
On the recommendation of my rheumatologist and another doctor I respect, I started taking alendronate a year ago. I have not had any side effects at all. I also purchased a vibration plate exerciser, and do regular weight bearing exercises to try and increase bone density. I just started Dr. Fishman's yoga program - 12 Poses vs Osteoporosis - to increase bone density as well. I do take calcium with Vitamin D and magnesium, boron and Vitamin K and eat more calcium rich foods.
So, I agree with others who have suggested you get a good doctor who specializes in osteoporosis and explore what other things you can do to improve your bone density and reduce the risk of fracture. There are physical therapists who specialize in osteoporosis and yoga instructors certified in Dr. Fishman's method - maybe there are some near you. Also you can find a lot of information by googling. I wish you the best.
