I am 28 years old. I have been having breathing difficulties since Aug of last year, by this I mean feeling as though I am not getting a satisfied breathe, some chest discomfort and tightness. I have seen several G.P's and an Asthma Nurse and have been on oral steroid treatments, anti-biotics for a possible infection and both a daily brown inhaler and a blue inhaler when required. My PF averages between 330-420. I have never been admitted to hospital but have presented myself there on several occasions but only once have I been put on a nebuliser. My pulse oxygen has always been between 97-99. Chest X-Rays showed slight inflammation. All medical professionals that have listened to my chest have said there are no obvious sounds of wheezing. I was referred to a respiratory consultant for a secondary opinion to see whether my problems were a lung issue or something else and she felt that I could possibly be suffering from GERD and was prescribed the necessary medication. Initially this appeared to alleviate my problems, until about a week or so ago when they have arisen again. My consultant recommended a 24 hour heart trace and a breathing test at the hospital and that if nothing showed up on these she wouldnâ€™t call me back due to the GRED medication (apparently) working. Due to the Christmas holidays and other things, I have only been to the hospital today for my breathing test. The Health Care Assistant who did this told me that my lung volume was fine. He asked whether I undertook regular exercise (which I donâ€™t) which he tells me he asked because it showed I have good lung elasticity? However there appears to be an issue with how my lungs are exchanging gases. The Health Care Assistant tells me that it should be 80-90% but mine read 66% on the first attempt and 73% on the second. He explained to me that my lung walls may have become thickened but gave me no further information. I am awaiting my next consultant appointment. I appreciate that this may not be the best place to ask but I was wondering whether anyone had any further information that they could provide me or point me in the right direct of some information. Initially I was told I may have asthma but now I feel I am in limbo. Any information would be greatly appreciated. Many Thanks!
