Hello everyone. After 8 years of no drugs, after losing most of my hair (all over body) on forteo and then getting LERD on fosamax, I got a dexa scan and ofcourse am back in osteoporosis range. Hip is -3.7 I wasnt ready to do a long term injection so started weekly Fosamax. Last week was pill #2. 24 hours later, I became so incapacitated with pain in both knees and back, I could hardly get home. The previous night I had horrible spasms that woke me out of sleep all up my legs and back. I realized this was Fosamax! Weds is my 3rd pill. I hope I can last 6 months on it. I know some have no side effects but this happened to me. If anyone had similar, what did you do? I read this can last a long time-- scary.
