Fell hit my head, having vertigo a month later pressure and nausea?

?If related: If the Vertigo is indeed related to the fall, you need to see the Dr. ASAP to assess for possible post concussive symptoms... or even a very slow bleed like a subdural hematoma (SDH), although much less likely if it was 1 full month . Best wishes.

Ct head: You really need a ct of your head to make sure you don't have an internal bruise!

Exam: May be suffering a mild concussion. This will require eval by your Dr to determine, but usually are self-resolving. Best Wishes Read: http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0001802/
