What Can Cause Headaches?

Since a headache (ache in the head) is such a generic term, it can be surprisingly difficult to define. Many conditions and circumstances can cause your head to ache, which also means that no two headaches are created equal. If you have a headache, it's always wise to consult with your doctor instead of self-medicating and "hoping it goes away." Most headaches are relatively minor, but some can be downright deadly.

Headaches can result from a wide variety of causes:

- muscular imbalance in the neck;
- side effects from many drugs, even birth control pills;
- blood flow problems;
- allergies or reactions to any number of chemicals such as cleaning agents, cigarette smoke, or caffeine (or the withdrawal symptoms from caffeine addiction);
- menstruation or hormone imbalances;
- temporomandibular joint disorders;
- mood changes such as anxiety or depression or panic disorder;
- head trauma or concussions;
- dangerous life-threatening conditions such as bleeding inside the head, stroke, brain tumors, or a heart attack;
- diseases as diverse as meningitis, diabetes, Celiac Disease, Lyme Disease, food poisoning, and more;
- working at the computer;
- or eye strain.

How do you know whether your headache is simple or actually life-threatening? In all cases, consult with Dr. Johnson.
