It ended up being fine, so let's put that out there right off the bat.
Yesterday I was shaken from my sleep with a terrible, pulsating headache. A pain I hadn't felt since I was in the hospital. I tried to ignore it, I even got to work. It just kept getting worse. It got to the point where I couldn't make any sudden movements or it would get worse. I couldn't bend down, it was horrible. After some prodding from my coworkers I called my primary, since at this point Milwaukee was closed. Long story short, the doc on call said to go to the ER because if I were to come see her that's where she would send me.
At this point my dear husband was already sent home from work - I had called and told him that I may be going into the ER. His boss kicked him out without waiting to see if I indeed was going to the ER. So he got home and we went.
After several hours, a CT scan, and blood test, everything came back normal. I was given morphine (after a VERY painful attempt in my right arm, they switched to my left), and told that if it persists I need to come back for a lumbar puncture. I am happy to report I am feeling much better today.
My only idea about why this happened is this: I ran for the first time the day before, it was a very short run and it was intervals so just 90 seconds at a time. Maybe that jarred something and caused it to inflame? The ER doc didn't think so, but that's my only idea about why this happened. It was a HUGE headache, i mean a monster. It makes me mad, it's been three months and I can't even go for a jog without paying heavily for it?
