When I was 17 I was diagnosed with Raynauds. I was put on blood thinners but eventually had to stop taking them because they made me sick. Since then I take a low dose aspirin. In 2005 I had a knee scope done to remove scar tissue around my knee cap. After the surgery I had more problems with my circulation but it was mostly on the same side as my surgery. I had numbness and tingling and cold foot below the knee. I was sent to a nuerologist but got no answers expect it was the raynauds. Til this day I have no answers but still the same problem. The weather has been very cold and even though I stay active and try to be healthy it still is bad and still mostly on the same leg. Is there something I am missing?
Tingling and numbness is a feature of nerve disease(neuropathy). As you have ray nods phenomenon since a very long time, which sometimes indicates that you may have some underlying hematological diseases. Though sometimes no cause becomes evident and we clinicians call it primary ray nods which is mostly harmless except some distressing pain on cold exposure. In your case I would suggest consulting a rheumatologist for better analysis of your situation. As a physician I would suggest you to avoid freezing exposure. Wish you a good health.
