V.N.
alternate heat and ice. 30 minutes ice, 30 minutes heat. leave both off for about an hour and then do the process like that several times. if that doesnt work, i would get it checked out. i think you can get one of those packs that go in the freezer from a rite aid or just your local pharmacy or walmart even maybe. they are like ice pack things, but you can also put it in a bowl of water and heat it up for several minutes for the heat part, those are amazing! hope things get better!
