“I usually feel ok, but I still keep getting sick too often”
Minor, early sinus infections are often called “acute sinusitis“. Usually these infections last 10 days or less and are usually thought of as being caused by viruses rather than bacteria. Sinus infections lasting longer than 10 days or infections that tend to worsen after an initial improvement are likely caused by bacteria and may require more specific medical treatment. Typically these infections are treated with a first-line antibiotic such as amoxicillin (however recent investigations as to whether this is necessary have been reported lately).
