If your feet are itchy and red, Blue Star Ointment is your friend.
Don't trust any doctors alive today, they have been screened to be people that need your money more than they need you.

This stuff cures mange in dogs.
Ringworm, too.

It is a 100 year old skin irritation formulation.
I use it all the time to tame flames in the nether regions and between the toes of my feet.
Amazing stuff.

Warning: The more it burns, the more you needed it.
Use it sooner next time, if it burns.
It usually quits burning in a day or two depending on the depth of the inflammation.
It doesn't burn the whole two days, just when you apply new.
It does stop burning in what may seem an eternity, but is really only a few minutes.
Use it sooner, if it burns.

Dose lightly at first to manage the burn, eh?

I didn't get the benefit of these words of warning, I found out the hard way, and then found out a couple more times, then I started keeping a steady supply to avoid the burning all together.
