I am 70 years old with diabeties and have any other health issues. I am on a blood thinner due to a mechinacial valve I woke up one night and have a blood clot on top of my foot. I sleep alone and not sure how I got it but I have seen the Dr and my foot was wrapped up and have done this for a week. my foot is all different colors due to this is their any thing I can do to help it heal better. It is still so sore. Do I keep it wrapped up or let the air at it? I have pain walking and putting a shoe on.
