What's a fast cure for chafing on inner thigh i'm a contractor so i sweat a lot and its a pain?

Friction cz's sores: The most likely reason for your problem is a combination of your sweating which reduces the natural lubrication of the skin and thus increases the risk of damage as well as the friction from your thighs rubbing. You need to consider wearing undergarments that completely cover these areas like boxer briefs, apply powder to the areas to absorb moisture/reduce the friction, and skin cream after work.
