I hit my head really hard about a week and a half ago. Ever since that day I've been getting very strong, intense migraines every single day. They are so bad that I can't hardly stand them and I cry. I never had them before. I've read online while researching this topic that I could've had a concusion when I hit my head and that I need to be seen by a doctor immediately. Also have read things stating possible bleeding in the brain. I'm really worried but I don't know if this is really that serious or not. Do I need to go to the doctor?

This is not a joke, GO TO THE ER RIGHT NOW. You need to see a doctor, and you need to see one now. Even if you do not have insurance, you need to go to the ER NOW.
