How big a wound are we talking about? It might be gross, but a photo might help us to better understand your predicament and the status of your healing.
Mimi's right - If you still have an open wound, keeping it moist will speed healing. But if it's been 2 months and it's still open, I'd be giving the Dr. a call to see what he/she thinks. Tegaderm and other similar type of bandages are great, can be left on several days, but they are on the pricey side, although worth every penny.
I personally have many reservations about applying honey to any wound.
Since cost is an issue for you, it would be worthwhile to compare the cost of 60 days worth of Vitaman E capsules (not to mention the messy application) with the simplicity of something like Mederma.
I speak from my own personal experience with wounds large and small. Obviously others will have differing opinions and recommendations. And some will just Google keywords and become an instant expert on the subject.
You have said before that you were diabetic, so you probably know that wounds take longer to heal than in non-diabetic patients. I would not mess around with this. If you want good advice, proper healing without infection, and minimal scarring you really should be talking to your doctor.
