AAgh! As a physio trained in the NHS but out of the country now I feel Britain fails to do enough for patients!
OK, have you got a good physio? Find one, private if necc. What about the orthopaedic consultant??? What did they say apart from 50% healed? Have you diabetes or something that delays healing? Follow up appointment? Sorry to ask but I can't give a prognosis, sounds a bit disastrous.
