Actually works for me now (in some situations), which is great news. I think the recent ops/changes in regime/medication means some of the underlying problems/pain is sorted so it's easier to just treat the pain that's there/muscle spasms or something. Anyway, am really rather happy about that. Reduced agony to mild aching in half an hour, not on it's own, diazapam and codiene also helped but I think it was more the tens then anything else.
