Really?

Well, my question today is....How long can a headache really last? I have had a headache for several days, but it just seems to be getting worse and worse. Sinus cavities are congested, but nothing will break it up. I have been taking Mucinex D for days now. I even did a nasal flush today with little affect...and it was horrible. I feel like just for the effort, all mucus should have given up and surrendered. If anyone had a miracle remedy, please let me in on the secret. I promise not to tell anyone-Girl Scout honor---well, I was never really an official Girl Scout, so to heck with that. Maybe I just need to see an ENT. I guess I will try to put my baby down for the night and turn in. Maybe a great night sleep will help. Hoping tomorrow will meet me with fresh air--that I can breathe---and a little better health!
