Hi Jrcn
I have pains down my left hip but I know it's the Met , the tamoxifen doesn't help , neither does the chemo, but as much as I hate to say keep moving even if it's at a snails pace.
I used to walk around the soccer field while my kids had their training session, kill 2 birds with one stone, maybe there is some laps you can came up with.( I started by myself by the end of season most of the soccer Mums had joined in going around in circles )
I also have an exercise bike at home , that I can do while watching TV.
Good luck
