This month I was told to get a bone density test. I guess I should have had one sooner...but I always felt so strong ,and healthy. Anyway, I went through menopause at the age of 40 ,I have been on HRT for 13 years. I ran for 3 years ,and did the Portland Marathon last year. I'm a thin build (125 lbs). Well I just found out 3 days ago, I have ostepenia in my hips. I was SHOCKED as I have fallen on the pavement from running several time ,and never broke anything. I have a lot to learn ,and measures to take to try ,and stop it. Fosamax has a lot of bad side effects. I'm in the dis belief stage right (when did I become my grandmother). I always felt so healthy ,and indestructible. I have a doctor appointment tomorrow ,to try ,and find some solutions. ; (( Im 52.
