Hi, 34 yr old male, 5 9 190lbs. At work 5 days ago I had a loud pop on the left side of my head (about 2 above and behind my ear). Immedately followed by an intense pain, bee sting on steroids, that spread to the top of my head and down my neck. It lasted about 3 secs. I was slightly light headed after, the next day, I went to the ER, had a CT scan and blood work done. Everything came back fine. However I have had the short intense stinging headaches and pressure build up in my head for the past 4 days....what s going on with me?
