Neuropathy. Peripheral neuropathy seems causes those very sensations. Swelling also causes this. If you have edema in your legs and feet, it compresses the nerves and also sucks up some of your body temp.
Leg pain. If your legs feel cold and you have hypothyroidism, ask your physician (p) to check your TSH to make sure your dose of levothyroid is appropriate. If not, you may need a higher dose. If it is, have your p order an arterial profile exam of your legs to see if you do not have peripheral artery disease (pad). If you have pad, have your p refer you for therapy. Speak to your p about your other issues.
