Hello doc, Sometimes usually in summers, I feel like I am unable to take long breaths. When I try to take a full breath, i feel something resisting the full breath, perhaps the lungs. I have got a fluffy stomach, so m wondering if something has gone wrong, may be lungs or stomach has got abnormal in size as just an assumption. Can you suggest what could be the probable reasons for my breathing issues, what tests need to be done if any. Thanks
