Symptoms of the sinus infection depend on if the infection is acute or chronicle.

In case of acute frontal sinusitis located above the eye region the most common encountered symptoms are painas in the forehead, fever and mucous nasal release. The mucus slips behind the internal nose down the throat and the patients sensation is of great pain while in a horizontal position; pains decrease when the person sits with the head upright.

Maxillary acute sinusitis is localized in the cheekbones on one or both sides of the nostrils. The patients complains are pain in the cheekbones, pressure on the cheeks, redness, tenderness and swelling of the region. The pains worsen when the head is held upright and lessen while lying down. Other signs such as pain inside the cheekbones, pain under or around the eyes, pain around the upper teeth and nasal discharge.

The etmoid sinusitis, located at the base of the nose right between the eyes, develops with nasal congestion and discharge, a feeling of pressure in the inner side of the eye or on the inner side of the nose. Also headaches localized on the temples on in the eyes region can appear; the sensation of pressure worsens while coughing, sneezing or lying down.

Acute sphenoid sinusitis lies behind the ethmoid bone and behind the eyes. The particular symptoms are intense pain on top of the head or behind it, fever as sign for infection, nasal discharge; the pains intensify when binding forward and the patient develops sight problems as the inner pressure extends to the brain.

The chronic frontal sinusitis evolves with constant but low intensity pains in the forehead area and major damages to the sinuses.
