Just an update if anyone is reading these.. My headaches did seem to go away shortly after those fires went away, so I'm guessing it was the smoke from the fires causing the headaches.
Well last weekend, which was a week after the headaches started, they seemed to go away for a few days. Then came back this last Monday and have been off and on again since then but not as bad. One other thing I noticed, That weekend I went biking, there was a fire nearby that had just started. Then after those few days of the headaches being away, another fire started and around that same time the headaches came back. So now I'm thinking it could be the smoke from the fires causing it, maybe.. I believe that second fire is out so I'll pay close attention and see if these headaches go away, if they continue I'll certainly look into seeing a doctor.
Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with a doctor.
Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
Without further information about your headache, it is difficult to provide you with adequate information. (There is information that would be needed to determine if this is a migraine, related to the structures of the neck/back, etc). Most likely, your headache is exertional related. However, it is important for you to understand that if you have not experienced headaches in the past and you are now having new head pains, seeing a neurologist is a good idea, just to make sure there is nothing serious causing this pain. Also, if you have had any injury to your neck, such as chiropractor manipulation or motor vehicle accident, you should have imaging of your neck and brain to ensure there is not a condition called dissection of the vessels. Lastly, if you are older than 50 years old, it would be helpful to get a lab called ESR checked. This would be useful in diagnosing a condition called temporal arteritis.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
