Husband hit his head on the scalp and bled also fainted.. 2days later he refuses to go to the hospital! should i be worried??

Yes - you should be: Head trauma associated with fainting suggests that the patient may have had a concussion. Further medical evaluation is indicated. I would suggest that you encourage your husband to be seen as soon as possible by an appropriate medical professional. If he can be seen right away by his primary care doctor, that would be acceptable. Otherwise he should go to an emergency room.

Fainting a problem: Does your husband take Aspirin or NSAIDS(eg Motrin)? Need concerned about concusion or subdural hematoma from bang leading to fainting. This diagnosis made if he begins to walk funny in a few days. Would seek medical attention when you can. Probably a Neurologist. He may be macho, not complaining of dizziness or visual changes. Subdurals can be managed relatively easily with simple Surgery.
