Hi, I am 33 year old female, from last week I am feeling pressure in my left Ear and sometimes I feel light chest pain, 3 days back while walking I start feeling heavy chest pain and heavy breath when I sit and took deep breath I got normal. That night I felt like something is stuck below my heart and was painful to move, next morning I had light pain and that become worst and I felt very high pain in left side of my chest, shortness of breath, and my heart beats was very fast and I tried very hard to control myself I sit down and took deep breath than slowly slowly I got normal and that whole day I had I light pain in left side chest after few hours I start having pain in lower back and lower belly. Still feel pressure in my left ear sometime less some time more, sometime light pain in left chest. What can be the cause?
