If the skin condition of your heels is severe and painful, a paraffin wax treatment may help and relieve pain.
It works like a natural emollient.
Melt paraffin wax into a bowl and add 2 tablespoons of coconut oil.
Mix well and allow to cool.
Dip your heels into the mixture for 5 to 10 seconds, then repeat the action.
Do this several times until you have several layers of wax on your skin.
Wrap your feet in a plastic film and leave to act for 15 to 30 minutes.
After this time, remove the foil and wax.
Repeat the procedure once or twice a week.
Good luck.
