My father aged 55 is experiencing vertigo since 10 days mainly every morning after wakeup first 7 days responded well with vertin 16 od but since last 2 days even vertin 16 BD is not helping much and even in evening vertigo is happening. Around 8 months back his brain MRI (regular checkup) and everything normal in brain showed right ear chronic mastoiditis though no other symptoms like ear discharge, pain ,redness, swelling present. He has hypertension but no medication running right now  though we will start soon and were taking readings( remains 140-150/85-95 in morning and 135-145/80-90 in evening ) . He also has cervical spondylosis (neck pain and shoulder pain since 1 year). Earlier also occasionally he got vertigo but once in 1-2 month only but now regular since 10 days. So tell whether we need to evaluate incidental MRI findings of RIGHT CHRONIC MASTOIDITIS or not needed as vertigo linked to Hypertension or Cervical or mastoiditis??? Heard mastoiditis can progress as well??
