I suspect that the reasons for joint/bone/ muscle pain and stiffness @Romla are not just down to any one cause. While I did have chemo, my Vit D levels were normal before and after. Maybe due to outdoor lifestyle on Sunshine Coast? So this obviously did not have any effect on my particular bc and did not cause my low bone density.
I did suffer from severe bone/muscle pain on Docetaxel chemo. I had what I thought was joint stiffness at first on Tamoxifen. I now wonder if that was not at least partially caused from muscle loss from the sudden reduction in my normal activity levels while on chemo, especially the last half on Docetaxel.
The joint stiffness gradually went away on Tamoxifen (as I returned to more normal levels of activity and also became much more into exercise!). But despite being very active, having good levels of Vit D etc, I had severe joint etc pain after 1 month on Femara! (After 2 years on Tamoxifen). I tried a variety of supplements before finding that Curcumin really worked for me, especially for my painful hands. (They used to wake me in the night just aching, swollen and stiff).
12 months into Femara my bone density (which was low to start with) was at osteoporosis levels in my spine. For me I think a big factor in this was the impact of Femara on my ability to move and exercise. Although I did walk a lot! Once I started a targeted weightlifting program to build muscle, which in turn builds bone, my bone density improved. It is now better than when tested before starting Femara. Incidentally my range of joint movement is better than it was before getting bc in the first place and this has vanquished any last bits of joint pain!
Our bodies are complicated and finding out what causes them to not be functioning well is complicated (and probably a very individual thing) for each of us. Always a good idea to check Vit D levels though. Very important for our health.
Hope the supplement does the trick for you @duxx1234
Good luck with your Chemo too.
