About 5 months ago , i had itching on my right foot calf , i rubbed my left ankle on it , it created a wound on the calf . I ignored it and expected it to heal itself but it didnt healed . Doctor suggested me , T-bact cream , it helped but not cured the wound fully , then he gave a antibiotic for a week . After a week of antibiotic wound cured almost 80% , but 20 % still exist even after 4 months , please suggest .. photo attached
