I have problem of migrane and sinus. So often my forehead pain and also the middle and sides part of my upper nose pain due to sinus problem. So in order to get rid of such pain and to divert mind from pain I apply tiger balm and vicks vaporab on my forehead and upper nose. This type of balm are for headache and they cause pleasant burning sensation to skin which aids in diverting mind from pain as you feel burning sensation over the area of pain.... But due to applying this tiger balm and vicks vaporub often now the dark black mark has been created on the middle of my nose, it look like a line from left to right on nose and look ugly. How can I get rid of it?
