Suggest Treatment For Dizziness

My 78-year old mother in Chennai, India, is suffering from dizziness the past few days. She has had this problem about a year ago and then it appeared to go away. She has seen a general practitioner and she has prescribed the drug Vertin. It appears to help. The dizziness is most severe when she is waking up in the morning. She fell down today, luckily back into the bed. I have been reading about the Epley technique and wondering if it would help her. Can I get a reference to a physician in Chennai, India who may be a specialist in administering the Epley maneuver? Because there is no drug or surgery with Epley, it seems to me like an easy action to take. Please advise. Thank you. This is my first time!
