wow this is an old post from me.. i should update everyone. it lasted about a week and 1/2. advil/aleve and a neck rub from my wife seemed to help and then one morning it was just gone..

i still have no idea why it happened... but i went to my ENT a little while after and he said it could be allergies or the massive post nasal drip i have.. i kind of don't think thats what it was because it was not a sore throat just sore muscles.. and i have been tested for allergies and i don't have any.. (any they test for that is) but it hasn't happened since.. *knock on wood*..
