Hello! Thank you for your inquiry regarding the hard lump behind your left ear and the associated symptoms of ear fullness and occasional pain. It’s understandable to be concerned about these symptoms, especially given your history of post-nasal drip and chronic cough. Let’s explore the potential connections and causes of your symptoms.

Firstly, the hard lump you’ve noticed could be a lymph node. Lymph nodes can become enlarged due to various reasons, including infections, inflammation, or even more serious conditions. Given your history of nasal issues, it’s possible that the lump is related to a sinus infection or another upper respiratory infection. When the body fights off an infection, lymph nodes in the area can swell as they produce more immune cells to combat the pathogens.

The sensation of ear fullness or blockage is often linked to Eustachian tube dysfunction. The Eustachian tube connects the middle ear to the back of the nose and throat, helping to equalize pressure and drain fluid. If you have chronic nasal congestion or post-nasal drip, this can lead to dysfunction of the Eustachian tube, resulting in a feeling of fullness in the ear and potentially contributing to ear pain.
Your chronic cough and post-nasal drip may also be indicative of allergic rhinitis or sinusitis, both of which can cause inflammation in the nasal passages and lead to secondary ear problems. When mucus accumulates in the sinuses, it can create pressure that affects the Eustachian tube, leading to discomfort in the ears.

In some cases, the hard lump could also be a sebaceous cyst or a benign growth, which can occur in the skin or underlying tissues. These are generally harmless but can become painful or infected.
To determine the exact cause of your symptoms, it would be advisable to consult an ear, nose, and throat (ENT) specialist. They can perform a thorough examination, which may include imaging studies like an ultrasound or CT scan, to assess the lump and evaluate your sinus health. Additionally, they can check for any signs of infection or other underlying conditions that may be contributing to your symptoms.

In the meantime, managing your nasal congestion may help alleviate some of the ear fullness. Over-the-counter decongestants, saline nasal sprays, or antihistamines can be beneficial. However, it’s important to use these medications as directed and consult with a healthcare provider if you have any concerns or if your symptoms persist.

In summary, the hard lump behind your ear and the sensation of ear fullness are likely interconnected, potentially stemming from your nasal issues. Seeking evaluation from an ENT specialist will provide clarity on the diagnosis and appropriate treatment options. Thank you for reaching out, and I hope you find relief from your symptoms soon!
