Headache Left Side

With a pain to bend over or turn the neck, headache on the left side last only three days a bit tarnished by Tylenol. I'm on antibiotics for another infection, therefore, does not seem to be sinus or dental problems. The pain all night and arose in the morning. Possible nodes swollen on this side?

you might have a clogged salivary gland.
A simple solution is to bite into a lemon or something extremely sour. It will flood the salivary glands, which sometimes takes the small crystal that has formed there. If blocked long enough, you can form a crystal there that should be surgically removed because it becomes too large to exit through the opening it. It's almost like a kidney stone.
First, try lemon and perhaps a couple of times to see if that helps.

Go get a massage will help.

it may be inflated, or you could have pulled a muscle in his neck. if it does not get better in a few days, see your doctor.
