Same situation, but no answer to offer. When I stand for a period of time, or walk (what used to be a normal amount), my legs start to ache (when I lay in bed it seems they throb or vibrate) and the soles of my feet hurt. Once I sit down, then try to get up, I have to hobble because of the effect on my walking. I had ACT - the T being Taxotere, a lumpectomy and radiation. The pain didn't start until 2.5 months after completing chemo. At least I know I have a 'sister' out there somewhere!
