Patient's Query

Hi doctor,

I am 18 years old. I am asking questions due to my curiosity. When I was a child of eight years, I had problems with my tonsils where one of my tonsil being bigger than the other. The doctor suggested me to remove the tonsils but the other doctor told me that surgery is not required for this cause as I was not facing any symptoms. After that, I do not had many sore throats like an excessive amount of sore throats for a year. I had it for a time or two. But whenever I went to the doctor, I was diagnosed with tonsillitis. During this year, I do not have any sore throat. I do not have any other symptoms such as bad breath or white spots. But I suffer from an allergic postnasal drip and heard that it is caused when one tonsil is being bigger than the other. I am very concerned regarding the cause as it should not be an obstacle in my life. I have done multiple blood tests and it does not show any kind of abnormality.

There is nothing to be worried about. There are certain criteria that need to be fulfilled for undergoing tonsillectomy. Mostly, the surgeons follow the guidelines given by SIGN (Scottish intercollegiate guideline network) or AAOHNS (American association of otolaryngologists and head and neck surgeons). If you are analyzed carefully according to these guidelines, then you will not require surgery. The reason for having a postnasal drip should be identified and in most cases, it occurs due to nasal allergy or GERD (gastroesophageal reflux disease) or both. It can occur due to allergic issues in the nose. There are some irritative substances entering the nose and it initially produces sneezing reflux to remove the offending agent out. But the nasal mucosa produces mucus to trap the offending agent as it should not go inside the lungs along with the breath. Irritative substances like dust, smoke, fumes, pollen, animal dander are some substances that are inhaled inside the nose. You need to take adequate precautions by wearing an N95 mask. You can take a tablet containing N-acetyl cysteine one tablet two times a day after food apart for the next ten days. You can tablet containing Fexofenaidine with Levocetirizine one tablet two times a day after food twelve apart for ten days. You can do salt water gargling eight to ten times a day for a month. Keep sipping the boiled warm water every two hours for the next one month. You can use Duonase nasal spray two puffs in each nostril two times a day for the next one month. You can have chronic silent GERD with LPR (gastroesophageal reflux with laryngopharyngeal reflux) where the acidic gastric contents reflux back into the throat causing inflammation, irritation, and laryngospasm. It causes a foreign body sensation in the throat. You can follow these steps for GERD. Follow a strict diet and eat on time. Avoid taking oily, spicy, and cold foods or beverages. Reduce your quantity of each meal and increase the frequency of your meals. Keep a gap of two hours between the meals and going to sleep. Maintain a left lateral position while lying down. You can use a syrup containing antacid one tablespoon three times a day before food for a month. You can take tablet Pan-D one tablet in the morning before taking breakfast for the next month. Taking plain medications will not provide you a long-term benefit and it results in recurrence of symptoms. Try to follow these precautionary measures to reach maximum benefits. It subsides within three to five weeks when the precautionary measures and medications are followed in a proper way.

Same symptoms don't mean you have the same problem. Consult a doctor now!
