Pain on Arimidex

I came off tamoxifen June 2017 and cycled through arimidex, letrozole, and then aromasin (side effects).  I was put back on tamoxifen but disliked it so much I essentially through a hissy fit and said no more.  I stopped taking it.  After getting a break and feeling well again, I agreed to go back on Arimidex.

I have been on arimidex now for three months and the joint pain is back.  In the beginning, I tried acupuncture but it seemed that the more the drug built up in my body, the less effective it was. I recently stopped acupuncture after talking with the acupuncturist (who is also a physician) as it was no longer working.  I went through 7 treatments in total but with little effect against arimidex.

The pain is worse in both my arms - shoulders and upper forearm.  At night, the pain is also in my right hip, knee and ankle, varying in intensity from night to night.  I haven't been on the post-breast cancer drug long enough to consider coming off but the pain is like a dull ache that never goes away and if I move the wrong way, it's sharp and painful.

I have not found acetaminophen, naproxen or ibuprofen helpful against the joint pain.  I've tried a few topicals with little relief (Icy Hot, Biofreeze).  I found penetrex to be somewhat helpful.  Salonpas is helpful for my hip bursitis but not useful for the arm pain.  I've tried products with arnica with little to no relief.

When I exercise, I ache but it's worse once I cool off and then try to do something.  My doctors keep telling me that I'll feel better if I keep at it...and of course, I need to lose weight.  

I'm only 54 and feel like I'm 90. 

My question: what have you tried to reduce the pain and what worked for you?  Diet?  Exercise?  Topicals?  Vitamins C or D?  Anything else?
