Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Some wild flies can bite you such terribly. As you are diabetic this wound probably is infected. I understand that you don t have money. You can go for the Grams staining, culture and sensitivity from the wound discharge. This can guide us for possible treatment. Once the antibiotics is taken accordingly than you can be recovers from the infections at earliest. Please take good care of wound hygiene as it is equally important in treating the infection. Please do regular cleaning and dressing for the wound. Betadine and dettol can be used for the dressing and polysporin used as anti biotic ointment. Please make a good habit of hand washing this will prevent future infection as well as treat the present one earliest. Avoid further injury to get rapid recovery. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
