Hi there. Thank you for posting your question with Healthcaremagic. I will do my best to help you.
Your mother is most likely suffering from tinnitus
. This is an inner-ear problem sometimes caused by a viral infection. If its accompanied by bouts of severe dizziness
) the we call it Meniere's Disease.
If this does not go away very soon then she need to see a doctor. An underlying cause should be sought and where possible, appropriate treatment given. Assure your mother that it is unlikely that there is anything serious behind her symptoms.
I hope that I have answered your questions fully and been of some help. If you have anymore questions please contact me again anytime.
Dr Andrew Rynne.
