I get the same thing in my legs and knees sometimes too. I believe it is poor circulation.
I know when I sit on my legs or sleep a certain way that cuts off circulation it is worse.
I would ask your doctor though to make sure you do not have other things going on as well:)
Mine are extremely cold to the touch and I haven't figured out what is going on yet. I am still looking into it. I don't know what perception would mean.
I don't want to scare anyone, but the cold and abnormal feelings ranging from burning to freezing CAN also be a symptom of multiple sclerois. It's worth getting checked by your GP then maybe a neurologist as well, Almost anything can be a first symptom of MS. There are many medication now to arrest (stop) MS pretty well where it is so it doesn't get much worse over time--if you start them soon enough. After having MS 36 years, trust me---look into it now. Best of luck and blesings too! Jane in Indiana
I have had cold legs for years usually more in my left leg I have tried leg warmers, blankets wraped around that leg. At times it is so cold I feel like it could just break off I have talked this over with my doctor and he says it is not poor circulation but doesn't know what is causing it I am very frustrated as no one can tell me why this happens
