Hi.im looking for some help as getting no where with doctors. I have had episodes of breathlessness since I was pregnant with my now 5 year old son. Since last august it has become worse. I get episodes where I cant catch my breath. I feel like I cant fill my lungs. Some times it lasts afew minutes and sometimes hours. I have had various blood tests, been tested for airborne allergies with no positive results,been given inhalers but told tgey dont think it is asthma as oxygen levels good and chest fine,im.on antihistamines and montukast which helps abit. They are trying to say its anxiety but its not! I react to fizzy drinks,alcohol and chocolate for definite but just cant pinpoint it. I did have labyrinthitus earlier last year and when.im struggling with my breathing it can make me lose my balance abit. Any ideas please?!
