The sites you have mentioned are the common places (axillary pits, palm of hands and underneath of feet) of sweating because of the presence of more sweat glands located than in other parts of body. In your case it could be due to less sweat glands present in other parts of your body which could be normal. Otherwise, you need to do a Thyroid
function or a complete endocrinology profile test to rule out any glandualr malfunction. Thanks.
