thank you for your reply. i have had numerous scrapping out of the bone. i had it also before i was operated on, when i had skin graft to close the open wound. in U.K doctors from Manchester said i have osteomyelitis of heal and kept on scrapping out of the bone and gave me IV antibiotics, stayed in hospital for 2 months, but no difference. so i decided to go India and the doctor took a swab and blood test and he said i have bone Tuberculosis. i took the TB course for 6 months then thier after the scrapping out of the bone then finally the skin graft. the opperation was successful completley healed, after suffering for 5yrs. since the operation its been 6yrs now and the heel is slight crack and a little bit of puss is coming out due to the oestimillitus. MRI scan is also done now will have biopsy in september. Please tell me what are your views, thank you very much
