During summer in coastal Karnataka sweating is common but excessive sweating sometimes get bruises and also act as allergic to skin. Whether such irritation due to sweating is a deficiency test of body balance or vitamin deficiency. If so what is the cure? Is this a phenomena in old ages as skin is hard and without oil? I want an answer form homeopathy because itching that I get sometimes invoke me to rub and reddish spread appear on my skin.
