Why do I get headaches when I work out?

• So I have never really workout all that much, but I started to this week. The first couple days I was perfectly fine, but then I workout with a friend who pushed me really hard on a leg workout day. I all of a sudden got this massive headache. I could not continue working out, when I would stop it got better but once I started again it would immediately get worse. Then the next day it hurt so much again that I couldn't workout at all. At first I thought I was sick or it was because I was new to working out, but then I looked online and it seems many people have this problem and I have narrowed it down to two things. Either I strained something in my neck, that hurts my head during physical activity, or I got a Primary Exertional Headache. My neck doesn't hurt, and I don't feel it in the back of my head, more of the whole right side. So I think it is a PEH. Does anyone know how long I should wait before I start working out again? Or is there something else wrong with me. Id like to get back as soon as possible because I was so excited to finally start working out. I am going to see a doctor in a few days, but I am afraid they might shrug it off or misdiagnose it seeing as it is kind of vague. Any help would be appreciated thanks

• Answer:

  Headaches are common when working out beause all of your body (including you brain) is connected so i think you might have tired you body out making your brain tier out so then it hurt. Hope this helped. :)
