My mother in law, Age 74 who is always looking tired. She is not able to sit, stand & walk for past 1 month. She is not able to take normal food & drink. But she has no body pain. She already had treatment from Dr. T. Arvindraj MD at Kanagamani Hospital, Ramnad, Tamilnadu 10 years back. He told her to take NICARDIA RETARD 10 MG TABLET everyday once after breakfast due to block in heart. He also told that she might have heart attack thrice. But she had no such feelings. After 2 years she visited at CSI Hospital, Manamadurai, Tamilnadu. Their doctor tested her and reported that there is no block in her heart, But they also advised to take NICARDIA RETARD 10 MG TABLET everyday once after breakfast. Kindly advise experts.
