Letrozole: Anyone have muscle pain as a side effect?

Every medication has a longish list of possible side effects. Many of us have taken letrozole for 5 or more years with few or very tolerable side effects. The main issue is loss of bone density, but that can be mitigated.

@mora305 can you get your pain evaluated before deciding it is from letrozole. I am having the same symptom right now in my left hip, radiating, and the doc thinks it is bursitis. I am having an MRI. I am not on letrozole or any aromatase inhibitor: it's been three years since I stopped!

I am getting an MRI on Thursday to evaluate the cause of the pain. But I think it's interesting that I have never had this pain before and when I started taking letrozole, it showed up.

I have already found a longish list of possible side effects for letrozole but that doesn't mean anything to me because I have had so many strange drug reactions in the past. For example, when I received the Pfizer Covid booster, I came down shortly afterwards with a full body rash of itchy hives. It took many weeks for the rash to finally dissipate.
