Letrozole: Anyone have muscle pain as a side effect?

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.

@nora305 I also react to most medicines. I tend to make a distinction between "reactions" and "side effects." I tried a generic anastrazole and had a reaction, then tried a generic letrozole and had a reaction, and then tried brand name and was fine. I later found a generic from a different manufacturer that I was fine with.
One thing I am sensitive to is polyethylene glycol, which was in the vaccines and is used in many meds, including ordinary ones like NSAIDs. Maybe you could get tested for that since it seems you may have had an actual allergic reaction.
