Headaches and congestion from mold and mildew are the result of a mold allergy, according to the Asthma and Allergy Foundation of America. A mold allergy is defined by MayoClinic.com as an overreaction of the immune system to mold spores. Someone with an allergy to mold and mildew will experience common allergy symptoms, such as sneezing, runny nose and congestion, when he comes into contact with the substance.
Mold spores are tiny particles, or seeds, that mold and mildew produce to procreate. The small particles are carried by the wind and can travel for miles. Mold spores are inhaled, aggravating the sinus cavity, which leads to sinus inflammation, congestion and headaches, according to the Asthma and Allergy Foundation of America. Sinus inflammation causes blockage in the person's ability to breathe through the nose and the ability to properly drain mucus.
Sinus headaches are the result of sinus congestion creating pressure in the head, according to the University of Maryland's Medical Center. Inflamed sinuses swell and press on the eyes, the ear and upper-teeth, leading to sinus headaches. Once the pressure is alleviated, the headaches subside.
Someone with an allergy to mold and mildew will experience similar symptoms every time she is exposed to the substance. Congestion symptoms include nasal blockage, sinus pain and postnasal drip. Sinus headaches feel like a dull, throbbing pain in the forehead, according to the University of Maryland's Medical Center. Sinus headaches are commonly misdiagnosed and are actually a migraine headache. Talk with a doctor for a proper diagnosis.
The Asthma and Allergy Foundation of America states that the most effective treatment for a mold and mildew allergy is avoid exposure to the substance. Avoid going outdoors during springtime and eliminate all mold or mildew in the house. The University of Maryland's Medical Center states that using a humidifier, saline sprays and inhaling steam two to four times a day will help with sinus headaches. MayoClinic.com recommends using a nasal lavage, or sinus rinse, to cleanse and moisten the sinus cavity.
Antihistamines and decongestants are the most common medication used to treat mold and mildew allergy symptoms, according to the Asthma and Allergy Foundation of America. Antihistamines address the allergy symptoms and decongestants reduce inflammation in the sinus cavity. Pain relievers are used to treat sinus headaches, such as aspirin, ibuprofen and acetaminophen.
