Hi My mother 67 has BP for about last 5 years. Recently it is discovered that she's complaining about noise in her ears like a sound similar to a gas leaking from the stove before we ignite it. Many times BP was recorded when this sound was severe but BP was normal at that time. However, this ear noise problem has happened over recently and it is felt 24 hours but fluctuating regardless of BP. Please advise any suggestions.
