Hi, Welcome to Health care magic forum.
The reason for the recurring ringing noise in the ears is chronic
cold due to
allergy, viral infection, leading to the
sinusitis, infection of the internal ear, and so on.
I advise you to consult the E.N.T surgeon for recurrence.
You may need to have an M.R.I. and other tests for diagnosis of the infection of the internal ear.
Avoid allergy and chronic cold, by avoiding the things allergic to you.
If there is sinusitis, or deviated
nasal septum, a small manipulation may be done.
Wishing for a quick and complete recovery. Thank you.
