My dad's 72 and already has some heart issues. Recently, he's been dealing with fluid retention in his lungs, and even though he's on all the necessary medications and seeing a cardiologist, we're not seeing much improvement. He can't sleep well, isn't eating much, and seems to be getting weaker. We're really worried. Do you think we should consult a pulmonologist to help with his breathing, or is there something else we should be looking into to help him feel better?

yes u can use it, visit ur physician for apprpropriate managent
