My hands and feet are constantly sweating and cold to touch...?

Sweaty hands & feet. You may have hyperhidrosis, which is caused by a hyperactive sympathetic nervous system, causing the sweat glands in the hands and feet to produc excessive sweat. Sweating brings your temperature down, which can make your hands and feet feel cold to touch. Cold extremities can be caused by peripheral vascular disease, raynaud's phenomenon or buerger's disease. Anxiety is another consideration.
