well, today I got a bad headache.  why is this thread worthy?

well, a couple weeks ago, I got a minor concussion playing football for my school (nothing I couldn't play through though, but it did hurt a lil'.)

Now my head is hurting again for some reason.

could it be a sugar headache? I mean I did have some cake earlier. But I don't know. any idea what it could be? I hope I don't have brain cancer or something. (not something to joke about!!!!!)

Go to the doctor... A friend of mine had the same problem after playing soccer, and the doctor found a small tumor on his head

One good advice: Do not go for medical advice to the internet especially not in a gaming forum. Looking in the net may be ok when you know what you have and want more information but with something as general as a headache you will only find 20 possible deadly diseases you could have.

If you suspect it is something severe go to a doctor. Although if you only had a headache for one day I would give it a day or two. (But do not listen to me for medical advice either).

As a person who has had a concussion before, you can have concussion headaches for weeks after. If you've had multiple concussions, then you could have them for months after.

Do not partake in activities that could lead to a blow to the head if you recently had a concussion unless you have been cleared by a doctor.

Headache? You don't know the meaning of the word.
I got a mole on the top of me noggin that I have had frozen off. This basically involves spraying liquid nitrogen onto my head, so:
Imagine the worst brainfreeze in the world and times it by infinity and your getting close.

I find i get headaches when im dehydrated or hungover, if you havent been drinking you probabaly need a glass of water!

being that you had a concussion not too long ago, I would see a doctor.

I'll also throw this out there. The more concussions you get, the worse it gets. It's common in hockey/boxing for players to get to many concussions to the point where they always have headaches, lightheadedness, loss of balance and other symptoms months and even years after a concussion.

Playing through a concussion is the worst thing you can do.

You should probably go to the doctors like everyone else is saying.

Go to a doctor. Probably nothing but there is one important condition that needs to be ruled out and only your doctor can do that.
