Letrozole - Year 2

I'm still struggling with mine.  My onc has said I can take a break but he'd prefer it as a last resort (my cancer was lobular and very fast growing so that may be why).  I've started seeing a rheumatologist who is great at listening.  Unfortunately, it's a trial and error thing to identify just how it's screwing me up.  Trialled a very low dose of Lyrica without effect and about to trial higher dosage to see if that helps.  If not, then we'll be looking at other meds that work on different pain receptors.  Codeine works beautifully but we know the issues with opioids.  Exercise can help - if I can do it, which is not always possible if the pain is too bad.  Swimming or aqua-aerobics is the best as there is so little impact while at the same time, being in water helps to stretch the tendons and ligaments.  I have tried many supplements such as glucosamine and fish oil but not successful (the oil may have been but I found I couldn't tolerate the amounts).
