I Have Been Sick With Head Cold, Chest Cold And

I have been sick with head cold, chest cold and flu like symptoms since December 16th. A couple of weeks ago, it went to a full blown sinus infection and infections in both ears. I have a history of chronic sinus infections until I had surgery 7 years ago. I am currently taking augmentin (on day 8), but the swollen glands, muscle soreness, headaches, ear aches, fatigue and loss of appetite are persisting. My headaches cover my entire face, similar to a sinus infection, as well as the entire back of my head. The muscles in my neck are so sore, I cannot turn my head well and the pain of it all often feels like it is more than I can handle. Ibuprofen if taken 4 at a time takes the edge off, but the headache, glands and muscle pain never go away. I get winded and do not have enough energy to make it through my day. Should I be concerned or patient?
