Your ENT doctor was right that clicking sound and pain could signify a tumour. But since you have been examined by him, that at least is ruled out.
This clicking sound and pain occurs due to blockage of the eustachian tube. The eustachian tube is a tube which connects the ear to the nose. Blockage of the tube, which can occur due to a tumour, but also due to other causes, can cause symptoms like yours.
You can try the following OTC treatment at home. Antihistamines
- Alavert 10 mg once daily (OTC)
Decongestants - Sudafed 120 mg once daily(OTC)
Xylometazoline nasal drops - Otrivin nasal drops 2 drops three times daily in both nostrils(OTC).
Another important home treatment is Menthol steam inhalation - add Menthol salts (available OTC) to a bowl of steaming water and inhale the steam two - three times daily - this will relieve the congestion.
Another thing that you should do as often as possible is called the Valsalva Manouvre. Take a deep breath, close your nose with your fingers, puff out your cheeks and then swallow, so that air goes from the nose into your ears, do this whenever you can, this will help to give you relief.
