Thanks for your question on Healthcare Magic.
I can understand your concern.
She might be having muscle spasms which is giving this chest symptoms.
But better to first rule out heart diseases because post menopausal women are at increased risk of heart diseases.
So get done ecg and 2d echo first.
If both these are normal then no need to worry for heart diseases.
Post menopausal women are at increased risk of calcium and
vitamin D3 deficiency and these can cause spasm too.
So get done vitamin D3 and calcium levels.
If deficiency then she will need supplements.
Don't worry, she will be alright. But first rule out heart diseases.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
