What are the potential causes of chronic, severe left-sided throat pain radiating to the ear and jaw with associated difficulty swallowing when standard diagnostic tests (blood work, X-ray, and throat swab) are normal, and is a montelukast/levocetirizine combination (such as Montair LC) an effective treatment for these symptoms?
Your symptoms of left-sided throat pain radiating to your ear and jaw could be related to conditions like temporomandibular joint (TMJ) issues, nerve irritation, or even acid reflux, which standard X-rays and swabs might miss. Montair LC (montelukast/levocetirizine) is primarily used for allergies and is unlikely to relieve this specific pain unless it is driven by allergic inflammation. Since your standard tests were clear, I highly recommend consulting an Ear, Nose, and Throat (ENT) specialist for a more detailed evaluation to help you find the right relief.
