Hi, I have started working out or should I say walking. Today I ran for two minutes after I had warmed up and I thought my head would blow off. Its like I had pressure real bad in my head. Is this normal or is it something else?  It happened about 3 weeks ago when I went fishing and reeled in a fish that was way out and my head started killing me. Pls. Help!
