Your symptoms sound mostly like a viral upper respiratory tract infection, but it is important to be evaluated by your doctor
. A viral infection can cause nasal drainage, swelling of the nasal mucosa, and subsequently a block in the eustachian tube which can then result in fluid buildup in the ear. In terms of your neck symptoms, often times a viral infection can cause slightly swollen lymph nodes. If this is the case you may feel a small lump on the back and can even feel like an enlarged thyroid. The fact that you had a normal thyroid stimulating hormone test confirms that your thyroid function is normal. There are some rare conditions in which the TSH can be normal or low and your thyroid function can be also low. However, these conditions are quite rare and we never assume that this is the case. I would suggest that you schedule an appointment with your primary care physician
. I think the first thing you need to have done is a detailed physical exam of your head and neck. Your doctor can determine if this swelling on the right side of your neck is a lymph node or something else. If he or she is unsure, then you may need to have an ultrasound
done of your neck to see what the problem is.
