I rubbed a sore on my foot approx two weeks ago and it seems to be having hard time healing. has a lot of redness around it. what should i do?

It just needs...: To heal up. I would apply traumeel cream (or ointment) to help promote healing. It is homeopathic and available online or at most whole foods stores. This is anecdotal, but I have been personally using it for myself my family and my patients for 25 years. It is very safe, so you can apply it as often as you want. Sometimes i will apply it four or five times a day on cuts on myself.

See: A podiatrist for exam and diagnosis. If you are diabetic i suggest you get checked asap for possible infection and even if not diabetic. Redness could be infection so get in!
