I have a problem of sweating on my face, especially on the fore head & both sides of nose while eating spicy food. Even I feel lite sweat on my face while smelling spicy food. I feel it weird that I could even feel very lite sweat while seeing cooking of spicy food. I had previously consulted a skin doctor for this, but he advised that the problem is not with the skin but may be with the nerves which sense the smell & advised to consult a MD.
