I need to take a deep breath

Ever since I can remember I have had trouble breathing. I need to take a deep breath which people think it's me sighing to catch my breath, but over the last 5 - 6 years it's worse. I can not do anything much strenuous, else I start gasping and on some occasions I feel faint and sink. The other day when I was tiding up the garden shed I only just made it back inside the house, managed to get a Coke and was able to have 1 mouthful before I felt I had to lay down on the kitchen floor. This lasted for about 10 minutes.

Do you have any idea because when I mention it to any of the doctors they seem to brush it aside after testing me on the asthma blow tube.

Kind regards
Tony
