Hello Angela, Oh ya, 14 yrs of having sinus headaches. Yes, they hurt bad. I used to get those type of headache very badly in my teenage years. My head would pound like your describing. Everything that you have mentioned I have gone through. Not as much now. I still wil get sinus headaches , but not as bad as they used to be. Sounds like you have a sinus infection to me.
Suggestion: try sinus rinses. You, can purchase them at pharmacy and drug store. They help to clear out nasal passage. That will help the sinus headache. Hopefully, that will be helpful. Brandi.
