Hi, Welcome to Health care magic forum.
As you describe, it appears that you might have got some congestion of the lungs, or pressure on the heart,
anemia, or gastric hyper acidity.
I advise you to consult a physician for diagnosis and treatment. you may need to have
X ray chest, E.C.G, and other tests.
I usually prescribe to my patient with such symptoms
omeprazole,
domperidone and
antacid gel.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods, to have good recovery, and resistance against infections.
Wishing for a quick and complete recovery. Thank you.
