Thanks for your question on Health Care Magic. 
I can understand your concern. 
Females are at increased risk of cardiac diseases after the age of 40 years. 
This is because of 
hormonal changes. After 40 years, when women approach 
menopause, estrogen level start decreasing. Estrogen is cardioprotective and hence females are at increased risk of 
cardiovascular disease after 40 years. 
So we should first rule out cardiac diseases in your case. 
So get done ecg and 2d echo. 
If both are normal than no need to worry for heart diseases. 
Possibility of 
musculoskeletal pain is more. So take painkiller and 
muscle relaxant drugs. Avoid strenuous exercise and heavyweight lifting. Apply warm water pad on affected areas. 
Don't worry, you will be alright. First rule out cardiac cause. 
Hope I have solved your query. 
Wish you good health. Thanks.
