UPDATE

Well yesterday I did go to the Chemists, bought some aspirin and a packet of condoms while I was there ;)

Still, this headache persists. Did some more checking and found out that some of the symptoms I have, like loss of full movement in my neck, my age, and family history, (my Mother died of a cerebral hemorrhage), may mean I have the secondary type of exercise headache! You know the one that leads to death.

I'm going to the clinic this morning to rule that out, but wanted to post this as I thought it was a good chance to get sympathy comments ;)
