This : This definitely sounds like a problem of decreased blood flow. In all likelihood, you have an arterial narrowing or blockage in your pelvis or leg. In many cases, these abnormalities can be treated easily using minimally invasive techniques. You'll need to be examined by a vascular specialist and have some testing done. In the meanwhile, it would probably be a good idea to start taking a baby Aspirin every day (assuming you have no allergies to Aspirin or history of ulcers or abnormal bleeding). This will reduce the likelihood of your arteries becoming completely occluded by clot.

Cold foot: If these are new symptoms that you are experiencing i would see a vascular doctor for further evaluation.
