Acute (Recurrent) vs. Chronic
Although both terms refer to sinus infections there is a distinct difference between the two. Acute (recurrent) sinusitis occurs when symptoms result in sinus inflammation that lasts no longer than 4 weeks. Chronic sinusitis symptoms, however, result in sinus inflammation that last at least 12 weeks. Often, a patient will need a professional to administer an advanced treatment to correct the underlying cause.
If you experience sinus inflammation that last longer than 12 weeks and do not see an improvement from over-the-counter and prescribed treatments, or if you develop a fever, green discharge or develop a severe headache you should see your doctor or an ENT specialist for a more thorough evaluation.
