Itchy Skin
One of the main symptoms of a Dermanyssus gallinae allergy is severe itching. The affected individual may experience persistent itchiness all over the body, especially at the site of the bite.
Redness and Swelling
People allergic to Dermanyssus gallinae often exhibit redness and swelling of the skin. The inflammation is typically localized around the area where the mite has bitten.
Blistering
A Dermanyssus gallinae allergy may also cause the skin to bubble or blister. These fluid-filled bumps can be painful and itchy.
Hives
Hives, also known as urticaria, are a symptom of severe allergic reactions. They appear as a rash of red or pink welts on the skin and can be extremely itchy.
Respiratory Problems
In extreme cases, a Dermanyssus gallinae allergy can also cause respiratory problems. This includes shortness of breath, coughing, wheezing or sinus congestion.
Anaphylaxis
A severe allergic reaction to Dermanyssus gallinae can result in anaphylaxis, a life-threatening condition. Symptoms include rapid, weak pulse, low blood pressure, and loss of consciousness.
