Hi.
The clicking sound could be due to a block in the Eustachian tube, the tube which connects the back of the nose to the ear behind the ear drum. This is commonly seen after/during an episode of cold. Taking a nasal decongestant and steam inhalation can help. However, if it continues, it may need to be investigated further using an impedance audiometry.
