My back, knees and muscles are very painful. I have gotten very weak as well. My chemo has been over for 2 weeks short of a year, radiation completed October 2009. I am going to PT and walking on my breaks from work. Can I do anything else to alleviate these sideffects? I.E. protien supplements(no soy!) or anything? I take a multivitamin, extra D and extra B complex.I also take ginko to try to get my brains back.
