[|Human|] My Grandmother who is 98yrs old has open sore between her big toe and second toe. The second toe started as a corn but later turned into an open wound that is draining blood. She has been on bactrium and cepflaxin antibotics. It still has not healed. She has used bactriban as well. She is not a diabetic.
[|AI|]  Hi, As your grandmother has been treated with oral and local antibiotics unsuccessfully, then, I advise getting further investigations to determine the nature of the open sores. I advise running examination of skin scrapping for fungal infection and biopsy of the corn-like lesion. Depending on the tests results, specific treatment will be advised. I also advise getting her blood vessels of the legs examined by Doppler ultrasound to exclude deep vein thrombosis and/or other blood circulation problems. Wish her fast recovery! Chat Doctor.
