I have always suffered from chronic headaches and nothing Excedrin Migrane, Aleve, Tylenol, Motrin ect ever worked. Head On worked for a little while but would leave my forehead chapped - THIS IS A MIRACLE! Trust me this is one thing you can NOT live without! I have used on my neck and shoulders when they are sore - like magic pain is gone. first bought this eight years ago and have found that the formula has slightly changed. The new formula is good but it’s not nearly as good as the original. It has decreased menthol as well as decreased oil of gautheria.but overall much nesseeery thing
