Running?

Today is a very dreary and cold day. During the weekend, I had very painful headaches so I was extremely discouraged. Somebody told my mom that eating 5 slices of cucumber every night before bed is supposed to keep away the headaches for the rest of the day. So we'll see how that goes.
On Saturday was one of my worst headache days, so in the evening I decided to try to jostle my brain out of the habit of hurting, so I tried to run around the block. Turns out, unfortunately, I could hardly get half way around. Before the Accident, I was an amazing runner and I could do a 5k on a whim. So, I tried again on Sunday and I was so much better! I could have run around the entire block but I didn't want to over do it. When I started my school the next day at the kitchen table, I started feeling faint and hyperventilating. Now, I was doing nothing but writing the word: Ectothermic. Anyways, I almost fainted, I started to overheat (it was cold and cloudy outside), and my head started to hurt. I told my mom and I laid down on the couch, and tried to relax. After about what seemed like forever, It finally went away and I rested my eyes for about 10-15 min. Feeling faint like that hasn't happened for like 3 weeks. So I guess no more running for me. Now I have to stick to bike riding and walking. Its alright, but its definately not the same. If anybody has any cures for headaches (besides meds.) comment and let me know, it would be a fantastic help.
