Hello,
This is Dr. Klarida Papaqako answering your question.
From what you have described, looks like you are doing the right things to your burning wound.
The area that is not healed yet must have been a deeper burning, or it is on the plantar/soft skin area of the foot.
If I was your caring doctor, I would recommend to continue the antibiotic if there is still skin damage, but if its already healed then continue using only
aloe vera, or any other cream with no smell and color.. Most important thing of healing fast though, is keeping always the skin clean and well moisturized.
Massaging your
scars with lotion will keep them moist, make them less sensitive and make your stretching easier. It may also prevent skin breakdown.
Taking some pain killers as
Ibuprofen 400 mg as needed, will help with the pain also.
Hope this information is helpful.
Take care.
