Welcome to Health Care Magic
The features could mean early heart failure
You need an X-ray chest / EKG / ECHOcardiogram
/ Blood tests - Electrolytes, cardiac markers, Kidney
function and so on. May be rate monitoring...
Some drugs like calcium channel blockers could also cause swelling...
You should see your Internist, as soon as possible.
It is better to be seen by a specialist and get assessed - than wait and guess.
Wishing speedy recovery
