If it is only in your feet and socks and such do not help, then what comes to mind is peripheral arterial or venous disease? Just a guess, maybe something to get checked out? If you're having circulation problems it could probably lead to the ill feeling?
Not really. I haven't noticed any weird colors except the blue varicose veins every so often. When it's cold outside or in the room, my feet are cold regardless of how many socks I put on. Heating pads and space heaters don't really satisfy the cold feeling, though they do help some. Infrared socks and silver socks have not worked for me and I know raynauds people supposedly have had some luck with them. I don't feel this in my hands so I don't know if it is raynauds and the other symptoms I had made me think it might be autoimmune or something. Hearing is bad, fatigue, cold feet, general ill feeling, etc.. Thanks for replying and I will check to see if raynauds is a possibility.
Do they turn colors? Do you ever notice one or more of your toes look white or blue? When they get painful are they bright red?
Check into raynauds.
