Infections of the sinuses and lungs Sinus infections, colds, flus, and other illnesses cause irritated and inflamed sinuses. As the sinuses swell, they might exert pressure on nearby nerves. When this happens, it might cause head paresthesia. Head paresthesia is a feeling of numbness or tingling that isn't due to any physical problem with the body. Sinus infections are very common and usually go away on their own without treatment. Medications can be used to treat sinus infections or reduce the pain and swelling associated with them. Antibiotics are recommended for severe cases or when there's evidence that the infection is spreading beyond the sinuses into the brain. Headaches are the most common symptom of a sinus infection. Pain, redness, and/or swelling of the face Pain in the teeth, forehead, or neck Pains that don't go away Allergic reaction to bacteria found in the nose, throat, or lungs Sinus infections can also lead to anxiety and depression. If you are experiencing symptoms that may indicate a sinus infection, see your doctor to prevent complications from developing.
