Should i exercise?

5 days ago i got hospitalized for gastritis and has been in recovery since. I have high- cholesterol history but last time i checked my cholesterol in my blood is normal (it was a little over a month ago). 3 days ago i ate bbq with my friends and today i ate bbq with meat, sausage and meatballs for lunch. And im having meatballs again for dinner. Cuz im afraid, i take a medicine to prevent high-cholesterol and then i feel so bloated and my feets are hurt. I'm afraid im having high-blood pressure or stroke, what should i dooo should i exercise?
