Actually it will be a month by now, so last month around 14th i started with this heaviness and suffocating feeling in breathing it went for a week, I was scared so I consulted a cardiologist. He just heard about my symptoms and said it is a case of acidity or gas. He suggested me 2-3 gastro medications but it didn't affect me then when I went outside my home I had difficulty in breathing but then after a few days it stopped. Now again whenever I lie on my left side i feel pain when I breathe idk what's the problem is it a muscle pain or what
