In a bathtub. fill it up with warm water up to your
ankles.
Drop in 10 drops of camomile or lavendar oil.
Walk up and down the tub till you are ready to shower and
sleep.
If no tub. just a basin and soak your feet.
Throw in some golf balls and roll your soles over them.
Might be the heat and your diet. Your body is simply trying to get
rid of toxins and working overtime.
Still, try to visit a doctor and describe your symptoms to be on
the safe side.
