Sinusitis
About 70 percent of the time, symptoms of acute bacterial sinus infections go away within two weeks without antibiotics. When sinusitis symptoms last seven to 10 days or more, it’s a good idea to see a doctor to discuss treatment options.Histamine produces common allergy symptoms such as itchy, watery eyes, nasal and sinus congestion, headaches, sneezing, scratchy throat, hives, shortness of breath, etc. Other less common symptoms are balance disturbances, skin irritations such as eczema, and even respiratory problems like asthma.If the symptoms last for less than four weeks it is termed acute, between 4-12 weeks it is subacute, and greater than 12 weeks it is considered chronic sinusitis. It sounds like your infection has lasted about two weeks so is an acute infection. Acute causes included bacterial and viral (most common) infections.
