I get frequent bad headaches causing me to be nauseous and sensitive to light. a doc i saw prescribed fiorinal (aspirin butalbital and caffeine) but it doesn't always work. thoughts?

Headache syndromes: Could be migraine, but other causes are possible. If its migraine, many good treatments taken daily can prevent them. Taking 3 tablets 200 mg Ibuprofen with food, plus 1000 mg Acetaminophen (tylenol) if needed after 30 minutes can help the acute headache. See a headache specialist.

Migraines: Sounds like you might be having migraines. Fiorinal is a great pain medicine for headaches. If it is not helping, however, i might suggest a drug called Imitrex (sumatriptan) to help get rid of migraines. Doesn't always work but worth a shot. If you are experiencing these headaches frequently, your doctor may consider starting you on medication to help prevent these headaches.
