question: Hello doctor, I am 29 years old. CT scan came up negative for problems associated with infection. I request for second opinion for possible hemorrhage/brain aneurysm or complications due to infection. I have attached the reports. Associated Problems: Tooth abscess.  Symptoms: Light headedness, severe migraine, ice pick stabs on top of my head and a feeling of something running on top of my head. Note:  I went to emergency room and was denied treatment due to the diagnosis of 'routine headache' and then discharged.
