...a word from your favorite "medical type"...
Medications may be used to treat sinusitis, especially when it is caused by a bacterial infection. There are varying lengths of treatment with medications—treatment may be as short as three days or last as long as several weeks or more. Medications most often used to treat sinusitis include a combination of:
Antibiotics, such as amoxicillin, which kill bacteria.
Decongestants, such as pseudoephedrine hydrochloride, which reduce the swelling of the mucous membranes in the nose.
Analgesics, such as aspirin, acetaminophen, or ibuprofen, to relieve pain.
Corticosteroids, such as beclomethasone dipropionate or prednisone, which reduce inflammation in the nasal passages. These medications may also be used as an inhaled nasal spray.
Mucolytics, such as guaifenesin, which thin the mucus.
At any rate, get thee to a doctor STAT for some meds. These things only get worse and feel like hell.
AFA original question, my unofficial guess is that for a lot of places, February is the "meat" of winter. People are colder, they're inside more, etc. as some have pointed out. Get well soon!
