I am 40 years old. I was hit by a car on 2/21 and had surgery on my left knee and shoulder. I developed a DVT problem in my leg. I am now taking 6mg of coumadin. Has anyone had a blod clot for this reason? Did the problem clear up after regaining your mobility? The doctor mentioned it could end up being a life long problem and I'm hoping it will clear up after I am walking again. Thanks for your help.
