Thanks very much - we'll have a go.
okphysio - what do you mean by a calf release technique? He did get v. occasional pain but more in the lateral head of gastroc not the medial.
He hasn't had any x-rays done and won't have any done for the meantime (at least 1-2 months) and there's no history of swelling.
No active trigger points in the calf or foot.
