Thanks for your question on Healthcare Magic.
I can understand your concern.
Since your mother is in perimenopausal age, she is at risk of heart diseases and heart diseases can cause similar kind of
chest pain which radiates to arm.
So first get done ecg and 2d echo.
If all these are normal then no need to worry for heart diseases.
She is also having
muscle cramps, so this can also cause similar symptoms.
So ask her two follow these steps.
1. Avoid movements causing pain.
2. Avoid bad postures in sleep.
3. Avoid heavyweight lifting and strenuous exercise.
4. Apply warm water pad on affected areas.
Don't worry, she will be alright with all these. But first rule out heart diseases.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your mother. Thanks.
