Differential Diagnosis for Bilateral Ear Irritation
- Single most likely diagnosis
- External Otitis (Swimmer's Ear): This condition is likely given the patient's symptoms of ear irritation and itching, particularly after a viral illness. The initial symptoms on the outside of the ear and posterior neck, which improved, followed by canal irritation, are consistent with external otitis.
- Other Likely diagnoses
- Eczema/Dermatitis: The patient's symptoms of itching and irritation could be related to eczema or dermatitis, especially if she has a history of skin allergies or conditions.
- Allergic Reaction: An allergic reaction to hair products, jewelry, or other substances could cause the symptoms described.
- Seborrheic Dermatitis: This condition can cause itching and irritation, particularly in the ear canal and posterior neck area.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Malignant Otitis Externa: Although rare, this condition can be life-threatening, especially in diabetic or immunocompromised patients. It presents with severe pain and discharge, but early stages may have milder symptoms.
- Ramsay Hunt Syndrome: This condition, caused by varicella-zoster virus, can present with ear pain, itching, and facial weakness. It requires prompt treatment to prevent long-term complications.
- Rare diagnoses
- Relapsing Polychondritis: A rare autoimmune disorder that can cause cartilage inflammation, including in the ears, leading to pain, redness, and swelling.
- Sarcoidosis: A condition that can cause skin and organ inflammation, including in the ears, leading to symptoms like itching and irritation.
