For the past few years off and on, I have a very difficult time breathing. at times its so bad I take really deep breaths and never feel like I can get enough oxygen. I also feel like I have a lot of gas in my body, but its not relieved when I belch.  I also have this pinching feeling on my upper left side of my chest..closest the arm pit but in the chest.  I get dizzy at times to. I have had EKGs, ultra sounds on my heart, stress tests..and there is nothing. I also cant breath laying on my back flat sometimes, and there is pressure on the back of my head. I get tension in the back of my neck and head after so long of struggling to breath. I am on day 3 now with no relief.  its done this many times before and lasted days, then went away for a day or two or even weeks, then returns.  I dont know what else to do? Doctors tell me I am fine, but its not normal to not be able to breath all day. There are a few times where I felt like I can breath, but it lasts minutes then its is all back.  I am at a loss..and almost broke..any suggestions?
Thanks for your question on Chat Doctor. I can understand your concern. Possibility of stress and anxiety related symptoms is more likely. But better to first rule out lung related diseases like bronchitis or asthma. So get done PFT (Pulmonary Function Test). If PFT is normal then no need to worry about lung diseases. Consult good psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor. Don't worry, you will be alright with all these. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
