Hi @Abbydog, yes potentially there could be side effects like muscle and joint pain. The jaw bone could be impacted too so dental hygiene is important. I guess like all medications there are side effects and don't we know it. I felt so good when I changed from tamoxifen to Letrozole nut inside my bone density has really taken a hit and I never thought I would be sitting here now with a spinal fracture at 60.
I guess in discussion with my doctor I agreed that having a fracture in my spine is a serious thing especially given I didn't have any trauma to get it. The worse I did was pick up my 15 month old grandson. I have to have these injections now because the risk of my fractures for me given my results of my bone scan are higher than the chance of the side effects from the injection.
