Hi! thanks for sharing your recent health problem with HCM! After going through your description, as I feel or if I were your physician, I would like to consider nothing but an infective pathology in this case! Regarding the scrapping, skin ulcer, soreness, hardness, color and painful movements, I must think that there is some recent infection only with soft tissue involvement and in worse case ti could be some kind of arthritis or inclusion cysts also! Therefore, you must see a physician for a clinical examination, dressing if necessary, rest and some antibiotics only! regards,
