6 Week Headache

I have had a headache on the right side of my head for 6 weeks now. It is mostly dull and at times it is a sharp pain. It becomes intolerable when coughing or sneezing. I can take Ibuprofen, Acetiminophen, Aspirin, and Naproxen Sodium with only short 1-2 hours of relief. A friend suggested it may be sinus related, so I took sinus meds with no avail. I would like to consider that I have been coughing and sneezing alot more due to Red Tide a block away from our house. Any suggestions?

any colored discharge from your nose? if greenish or yellow - could be sinus infection.  you want to get it checked out because if it could be more then just a sinus problem - ie: a small hemmorage or TSA problem that would need more attention... best to see a doctor
