hello and welcome to HCM,
You seem to have a chronic ear problem which must be properly examined after cleaning the ear canal
so that a permanent solution can be given to you.
You need to go for an ENT consultation who will request for an audiological assessment along with a CT of the temporal bone
to analyze the middle ear pathology and based on these reports the final treatment can be decided upon
Meanwhile please do not meddle with ear buds and do not allow water to enter the ear canal especially during head bath.
hope you recover soon
Dr Sriram Nathan
