Persistent Throat Foreign Body Sensation: Causes and Next Steps - Otolaryngology

More Info

---

The sensation of a persistent foreign body in the throat, often described as a lump or discomfort, can be quite distressing and may have several underlying causes. Given your history of allergic rhinitis and post-nasal drip, these conditions can certainly contribute to the sensation you are experiencing. Post-nasal drip occurs when excess mucus accumulates in the back of the throat, leading to irritation and a feeling of fullness or obstruction.
In your case, the fact that you have undergone both an ENT (ear, nose, and throat) examination and an upper gastrointestinal (GI) endoscopy without significant findings is reassuring, but it does not completely rule out other potential causes. Here are some possibilities to consider:
1. Laryngopharyngeal Reflux (LPR): This condition occurs when stomach acid flows back into the throat, causing irritation and inflammation. Unlike gastroesophageal reflux disease (GERD), LPR may not always present with heartburn, but it can lead to a sensation of a lump in the throat, chronic cough, and throat clearing.

2. Muscle Tension Dysphonia: Stress and anxiety can lead to muscle tension in the throat, which may cause a sensation of tightness or discomfort. This is often exacerbated by poor posture or prolonged speaking.

3. Allergic Reactions: Allergies can cause swelling and irritation in the throat, leading to a sensation of a foreign body. If you have not already, consider discussing with your healthcare provider the possibility of allergy testing to identify any specific triggers.

4. Psychological Factors: Sometimes, the sensation of a foreign body can be linked to anxiety or stress. This is often referred to as "globus sensation" and can be exacerbated by emotional factors.

5. Chronic Inflammation: Conditions such as chronic sinusitis or chronic pharyngitis can lead to ongoing irritation and discomfort in the throat, contributing to the sensation of a foreign body.

Given that you have already consulted with specialists and undergone relevant examinations, the next steps may include:
- Follow-Up with an ENT Specialist: If you haven't already, consider a follow-up appointment with an ENT specialist for further evaluation. They may recommend additional imaging studies, such as a CT scan, to assess for any structural abnormalities or chronic sinus issues that may not have been visible during the initial examination.

- Trial of Treatment for LPR: If reflux is suspected, a trial of proton pump inhibitors (PPIs) or lifestyle modifications (such as dietary changes and elevating the head during sleep) may be beneficial.

- Speech Therapy: If muscle tension dysphonia is suspected, working with a speech-language pathologist can help address any muscle tension and improve throat comfort.

- Psychological Support: If anxiety or stress is contributing to your symptoms, consider discussing this with a mental health professional who can provide coping strategies and support.

In conclusion, while your previous examinations have not revealed significant issues, persistent symptoms warrant further investigation and possibly a multidisciplinary approach to treatment. It is essential to communicate openly with your healthcare providers about your ongoing symptoms and concerns to ensure a comprehensive evaluation and management plan.
