I have been using it till many years and it is a great pain reliever . whenever I get hurt I apply this and it works . it starts its action within 10 minutes . the results of it are satisfyinh. it is very cheap and worths what it costs. it is good for kids as well as old people and everyone. it is good only for temnporary pain but if you break you bones it will not work because its made only for small injuries.
