Exercising on Friday backfired.  The workout was great but later I had excruciating pain in every bone in my body.  Not usual muscle pain that is normal after a workout but extreme bone pain, especially in my legs.  Had to use a cane on Saturday to get around.  Things are a little better today.  I am walking on my own but I extremely fatigued. Probably won't work out again until I talk to my oncologist on Wednesday.  Not giving up, just being a little cautious.
