Hi, I hit my head yesterday on the top of my car at around 5:30 pm, it hurt, I got a mild headache took Motrin I felt fine, then I hit my head again today at 2:30 pm. Since then my head feels like I have pressure in the center of my head and around my nose, kinda like sinus headache. My question is should I seek medical attention and go the ER? Is it okay to fall asleep?
