@BoraBora I did that exercise with my Oncologist, he pulled me off Arimidex for 6 weeks but had to go straight back on it regardless. I kept a diary and I was improved but he did say it would take 2 weeks to know and it did. Within a few days of going back on it, the pain seemed to flare again. I'm now switched to Aromasin, but it is EXACTLY the same! I've been seeing an Exercise Physiologist for about 8 months now, and we had a really good talk yesterday about it all. She believes it's the chemo more than anything, she said it attacks absolutely everything in the body, the sheath that goes over the muscles throughout the body, it shrinks causing cramping and pain alot. She's had clients torn their fascia muscle in their leg because it shrinks. The meds make no difference to my hot flushes, I was getting them in chemo before I started meds and they didnt alter off Arimidex uuugh!!! So the meds do attack joints, that's their biggest problem and it seems with combination of damage from chemo this seems to be where I'm at. She did say it will improve, so she gave me this spikey ball that when Im sitting to run each foot across it, it hurts! but its about stretching the tendon as chemo disintegrates the collagen in the foot. OMG crazy isn't it? she believes in time it will all come good though. I have good and bad days, no two are the same. Hugs Melinda xo
