Hello. Sorry to hear about your pain on Letrozole. I also started out on that AI, and developed carpal tunnel syndrome as a side effect a few months later. It got better after wearing wrist splints every night for 6 weeks and switching to another AI (I didn’t want surgery).
I eventually tried all AIs, and each gave me different side effects, last one being high blood pressure. And I also have brain fog and bad memory from these drugs, so you’re not headed for dementia thankfully.
These drugs do affect the whole body in a negative way. They’re not easy to take at all. I hope you find some alternatives like what Arpie suggested, to help relieve some of your issues caused by them. I stopped mine last year after 3 years on them (and don’t regret it) but that seems to be a controversial topic and not many women are brave enough to, understandably so. It took me a lot of thinking and analysing to make that decision.
Good luck with it 🤍.
