hello sir and welcome to HCM,
You have constant ear discharge
and you also have elevated blood pressure.
Both these problems can cause light headedness and dizziness
As far as your elevated pressure is concerned you need to immediately consult an physician who can control your pressure gradually
As far as your ear discharge is concerned, any strong antibiotic given after a test called the culture and sensitivity of the ear discharge can temporary stop the discharge.
After the discharge stops you need to consult an ENT and get a full examination of your ear drum to know the status and treatment measures.
Furthermore only a CT will diagnose a bony lesion and give further clue to your ear problem so go for the same
the further treatment of your ear problem will depend on the test reports
take care and get well soon
Dr Sriram Nathan
