Ever see someone start a fire by rubbing two sticks together?
That's what chafed thighs can feel like.
According to Allure, the rashy redness that comes from chafed thighs comes from friction, pure and simple.
The friction generated from walking or running rubs the top layer of skin off.
Ouch!
To treat chafed thighs, go home and take a warm or cool shower.
Use gentle soap and do not scrub.
Next, pat the affected areas dry.
If it's at night, put on a thicker topical, like Vaseline.
For day, choose something lighter, such as Desitin.
Next, relax and stop moving your legs!
It should clear up on its own, but if they become red, swollen, sore, or show pus bumps, see a doctor.
