When it comes to understanding lumps in the neck, particularly in the context of lymph nodes, it's essential to consider various factors, including the characteristics of the lump, associated symptoms, and potential underlying causes. Based on your description, you have noticed a movable lump in the upper right neck, approximately the size of a peanut, along with symptoms such as a dry throat, yellow-green phlegm, and occasional blood-streaked sputum. Additionally, you mentioned experiencing a sensation of fullness in your right ear.

Lumps in the neck can arise from a variety of causes, and lymph nodes are often involved in the body's immune response to infections or other conditions. Here are some possible explanations for your symptoms:
1. Infection: The most common cause of swollen lymph nodes is infection. This can be due to viral infections (like the common cold or flu), bacterial infections (such as strep throat), or even dental issues, as your doctor suggested. The presence of yellow-green phlegm and a dry throat could indicate a respiratory infection or sinusitis, which can lead to lymphadenopathy (swelling of the lymph nodes).

2. Allergic Reactions: Allergies, such as allergic rhinitis, can also cause lymph nodes to swell. If you have a history of allergies, this could be a contributing factor.

3. Dental Issues: Dental infections or issues with teeth can lead to swollen lymph nodes in the neck. If you have any dental problems, it might be worth consulting a dentist.

4. Benign Conditions: Sometimes, lymph nodes can swell due to benign conditions, such as reactive lymphadenopathy, where the lymph nodes enlarge in response to inflammation or infection without being indicative of a serious condition.

5. Malignancy: While it’s understandable to be concerned about the possibility of cancer, particularly nasopharyngeal carcinoma given your symptoms, it’s important to note that not all swollen lymph nodes are cancerous. Factors such as the lump's mobility, tenderness, and the presence of other symptoms can help differentiate between benign and malignant causes.
Given your symptoms, particularly the blood-streaked sputum and the sensation of fullness in your ear, it would be prudent to follow up with a healthcare provider. They may recommend further evaluation, such as imaging studies (like an ultrasound or CT scan) or possibly a biopsy if there is a concern about malignancy.
In general, you should seek medical attention if:
- The lump persists for more than two weeks without improvement.

- The lump increases in size or becomes hard and fixed.

- You experience significant weight loss, night sweats, or persistent fever.

- You have difficulty swallowing or breathing.

It's essential to communicate openly with your healthcare provider about your concerns and symptoms. They can provide a thorough examination and guide you through the necessary steps for diagnosis and treatment. Remember, while online resources can provide information, they cannot replace professional medical advice tailored to your specific situation.
