Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of viral upper
respiratory tract infection (URTI) is more.
And
chest pain is mostly due to
musculoskeletal pain.
But since you are having strong family history of heart attacks and
stroke, better to first rule out heart diseases for your chest pain.
So get done ecg and 2d echo.
If both these are normal then no need to worry for heart diseases.
Take antihistamine and anti inflammatory drugs for URTI.
Drink plenty of fluids orally and keep your self hydrated. Avoid oily and spicy food. Do warm water gargles 5-6 times a day.
Avoid movements causing pain. Avoid bad postures in sleep.
Don't worry, you 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.
