Rain and Headaches

I took my chances with not taking an umbrella this morning. Things were looking good until I got to the intersection of Congress and State. That is when the rain pour down and left me a bit soaked. I used my coat's hood to keep my head dry but the rest of me was pretty wet when I walked in the door. Other than the rain, I had a good commute. I have had a pounding headache in my right temple for several days. Should I be concerned?
