Headache Pain

I have a dull pain in the left side of my head. It was bad all day. I had a very stressful day yesterday, which consisted of about nine hours and stress of city driving. I was exhausted and was too stressed to eat much. Ive been eating today, but I'm still a little hungry and very tired .. It's a little nagging pain, but not really annoying. My nose is blocked, so it could be sinuses??

Sounds like a typical stress headache. Not bad, you want to relax in a dark room. but strong enough to let you know it's there. Sinus is usually at the front of the face, forehead, or lowest, or near the eyes. Take aleeve, it should reduce the pain.

If it was the left side of your face or forehead, then you should consider the sinuses, but if the left side of your head, then it is something a little more complex.
The seal sets your jaw to the head of the seats in right a little below and in front of your ear cavity. In the cavity such that you can find a very complex group of organs whose nerves are nearly related to the other in charge of most parts and organs of the same side.
When you have an unstable bite and teeth, especially molars, contacts, before any other, causes your jaw to slide and reality crash against your head (to be precise, the town is through a contact violent). This kind of hurts to touch the organs inside your ear cavity and causes pain, which ear reflexes world, in many cases around the eye, this whole area can go through the pain.
This is usually at its peak when the person goes through a stressing situation, because the stress causes the muscles of mastication is contracted much more difficult than usual.
Tips: Try to go to the dentist, a specialist on the bite, get a check and start getting the predicament of your life.
Try to remember if this happens every time you go through the stress or even when you worried about something.

# Drink about a half gallon of water per day - the head of neurorology at UCDavis (10 years) compared to a car low on oil to a body low on water (engine seizing).
# 2 daily muscle relaxant (1 or 2 shots of molasses or 1 or 2 bananas), they contain magnesium and potassium.
Massage # 3 - professional or read the Trigger Point Therapy Workbook by Davies (he teaches you how). The principle that causes headaches whatever serious is that the muscles knots (trigger points), which makes the muscles stay tight, which press on nerves.
Your back, shoulders, neck and around your head will certainly play into the cause and it will take some time to get all the trigger points to go.

I would try rinsing with a saline nasal (no spray). A lot of hot rinse water is salty in one nostril and others. It pulls all the dirt and shrinks the tissue (like swimming in the ocean). The buffered salt does not "bite" as much as plain salt water. You can use a new method as Nasopure, or vintage, Netipot.

You do not need a prescription for this therapy. If you live in a state like mine, they are about "outlawing" medicine Sudafed. Without drugs "is really the way forward on a common use.
