Thanks for your question on Health Care Magic.
I can understand your concern.
Lexotan is having benzodiazepam group of drug.
It is mainly used as anxiolytic drug.
Since you are improved with single dose of this drug, possibility of stress and anxiety related symptoms is more in your case.
At your age of 50 years (menopausal period),
hormonal imbalance can cause stress and anxiety.
And these can cause palpitations, flashing
chest pain and left arm pain.
But better to rule out heart diseases first because you had PVC (
Premature Ventricular Contraction) 1 year ago. So get done fresh ecg and 2d echo. If both are normal then no need to worry for heart diseases.
Get done hormone levels to rule out hormonal imbalance.
Consult psychiatrist and get done
counselling sessions. Counselling plays very important role along with anxiolytic drugs for control of stress and anxiety.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
