Hello,
Thanks for the query to H.C.M. Forum.
Diabetic foot ( ulcer over foot due to
diabetes).
Three type of diabetic foot is there as,
1. Neuroischemic foot ,in this
occlusive vascular disease is the main reason ,pain at rest,ulceration at margin of wound ,
necrosis,gangrene.
2. Neuropathic foot, in this type usually there is no pain but ulceration, this type of wound is warm,dry, painless and pulsation is there.
3 Infected foot ,most common problem in India,usually black due to necrosis.
Your 's father wound seems to be this type of wound.
Now your query is how to treat without surgery.
Yes, this is possible,
consult a diabetologist and sterile dressing after cleansing with povidone and high antibiotics ( gram --ve,gram +ve, anerobes) is advised.
Control of diabetes is must.
Healing of wound will take some more time as an ordinary wound because of diabetes.
Don't be panic your father's would be alright.
Good luck .
Dr. HET
