question: There s a tingly feeling left side of my head above my ear; it feels like a coin had been stuck in there. It s not going away for 3 weeks now. I had been in a car accident, hitting my forehead but I do not see no relations as I do not feel pain, just discomfort. It hurts whenever I think of it. I also get nasal congestion when I sleep on my left side. Haven t been wearing my eyeglasses for that 3 weeks. No throwing up, no pain behind/above my eye. Started behind my ear when I got anxious, now right above it. I am only 22, fairly large. Do you suspect aneurysm? What do I do to find out? Thank you doctors!
