Headache after working out.

Bump. Mine aren't as bad as yours sound, but I'd like to know what is causing my post-workout headaches.

Dehydration?

This happens to me sometimes when I am lifting weights. Hmmm, I guess it's probably normal in my case. Maybe ask your doctor.

Make sure you are breathing properly during workouts as well.

Dehydration?

I would go to the doctor and get checked out. Having blackouts during exercise could be a deficiency of some sort or something serious. You could have low blood pressure, a heart condition...there are tons of things that could cause this. Either way, a doctor can do a stress test and verify that all is well and you're not causing harm to yourself.

Here's a website that talks about this topic: http://www.livestrong.com/article/492013-exercise-blacking-out/

I used to get those, and it's because I wasn't getting enough sodium. I drink tons and tons of water and I'd go and sweat like crazy. I'd replace that with more water. For me, it's easily fixed by eating a handful of salted nuts or pretzels. Or even a gatorade but I don't much care for those.

Sounds like you may be clenching your jaw or otherwise tensing the muscles in your head, neck and/or shoulders.

1st thought - dehydration (by the way, too much sodium in your diet that's not diluted with enough water intake is the same thing as dehydration)

2nd thought - you are straining too much and not breathing properly

3nd though (could be related to #2) - blood pressure issues. My gym buddy has high bp and when it's bad she gets headaches after a workout.

Migraines and dizziness are not something to frig around with! I know it's going to be a pain to deal with the med bills but seriously!! Either get yoursef to a doctor or stop working out!

P.S. If it is high blood pressure, high sodium foods sure aren't going to help things either. Be more careful with your diet and do something different for exercise for a while and see if that helps.

I have migraines and sometimes get headaches too when I work out. Since it doesn't happen every time, it's hard to chart and work out the why of it. Last week I'm pretty sure it was the weather and the fact that I was having sinus issues(couldn't breathe).

Since you say you can't afford a dr. visit, I would suggest you start charting when you have your headaches, how bad they are, and what activities you were doing when you got them, what you've eaten, what the weather was like, even the temp of the room you are working out in....what ever you can think of that may change from one workout to another, and hope to see a pattern emerge.

Sometimes I get lucky and a light workout will actually cure a headache too. Migraines are so frustrating! Good luck to you!

I would go to the doctor.

I was having the same issue a few months ago and I found out it was caused by a few things:

1. The BC I was taking caused migraines. Mine were REALLY bad after working out. I had my doctor change my medication.

2. I was having really high burns and not eating enough. Especially carbs before working out. Need carbs for energy!

3. Low on electrolytes. I started drinking powerade/smart water before and during work outs.

It may be something else, but these are the most common reasons according to my doctor. But to be safe I would book an appointment with a free clinic or something.

I suffered from major headaches after every high intensity workout for months. After asking about this, I found it was actually to do with my job. As I worked on a PC all day and spent a lot of time looking down - my neck muscles had shortened and tightened. When my blood pressure rose during exercise - the blood and oxygen could not get through to my brain due to the tightened muscles and this was causing the headaches. There is a technical term for this which I cannot remember.

After visiting a masseuse for a couple of very painful sports massages and tips on stretches that I can do prior to high intensity exercise - on the whole these have cleared right up.

I would suggest if you are working on a PC on a regular basis that this option be explored.

Abnormal breathing patterns such as short, shallow breaths cause you to use secondary respiratory muscles more than your diaphragm. Those respiratory muscles are directly connected to the cervical and cranial portions of your body. With increased activity and tension in that area, headaches, dizziness and feeling lightheaded may occur.

I'd suggest that you focus on your breathing and see if that helps. If not, seek the opinion of a medical professional.

It's probably from low blood sugar, try to make sure you have some carbs, an hour or 45 minutes before a workout, not 5 minute before. If you take in a large carb intake just minutes before working out, your body is going to spike the insulin, dropping your blood sugar levels and making you hypoglycemic, which could cause these headaches. If that's not it you are probably just not breathing very well and its a lack of oxygen in your brain.
