spread oohh yeah.. it started in my right lower leg and foot now its below my belt line. every where. and is oddly worse on the left side. also it speed o my left arm, and previous surgical sites. I wish it wasn't so. problem with me is I'm on comp and they still won't accept additional sites for treatment. off to court i go...remeber this while you go through . you compromise your body to supplement your injury, it is possible it is fatigue and soarness from new usage. good luck
