FWIW, I had first in JanuDXA scan in 2014 at age 57. I didn't find out the results until 2016. I was told I had the bones of a 70 year old woman at age 57. Fosomax from 2016 to 2019 until it caused bad gut issues, so I stopped. I'm still left with gut issues from that. I read in a white paper that Fosomax stays in the body continuing to work for 10 years after you stop. That it also pulls from the femurs to fee the hips and pelvic region. That was years ago and I cannot locate that same white paper. Judging form the surgeon's comments and sort of odd behavior I feel that white paper was right.
I broke my femur in January. It snapped like a dry branch even after years of exercise, good diet, all the right supplements. The femur broke in midfall, not when I hit the ground. So finally got apporved for Forteo after a 2 month struggle with insurance. Began treatment 2 April. That first injection , after 5 to 10 mintues , severe bone pain in lower lumbar and pelvic region of my back. It lasted for about 20 minutes in intensity then began to subside. My husband panicked and called 911. By the time the ambulance got there, it was already simmering down. I was left with a headache and nausea I managed with meds. My doctor said stop so I did. A week later, after giving it thought, I knew there was nothing else I could take so I decided to tough out the pain until my body adjusted. I was fully expecting the same reaction. 7 days between 1st and 2nd injection. My doctor gave me the green light. So far, so good, no really bad anything. Minor headaches and/or nausea and other days nothing. Some fatigue. I don't have a choice, this is the only medicine that seems promising. According to the PA for a followup after my surgery, she said I fell in the rare 5 to 10 % of people who have that sort of reaction.
Prolia and Reclast are off the table due to how bad my osteoporosis is. I can't risk my other femur breaking. I've given birth twice with no meds and would rather go through 10 more no meds births than break a femur. It was the worst pain ever. Everyone is different, so take my experience for what it's worth. I'm glad I decided to push through with the Teriparatide/Forteo.
