Hi,im a 22 year old male and i've been dealing with this constant shortness of breath for over 6-7 years now. I written on a forum about this before but just hadd to write one again. Its hard to say but doctors have no idea what's wrong with me.I see so mnay people dealing with this problem and it seems like theres no diagnosis. It just strated outta the blue I went to take a deep breath and i couldnt get that last bit of hair to satisfy the breath and this whole vicious cycle started. After that for about 2 years i was constantly taking deep breaths and not able to get a satisfied breath. I WAS CONSTANTLY YAWNING>SIGNING AND TAKIN UNSATISFIED DEEP BREATH ALL DAY LONG. I had reached the point when i was staying home in my bed just hoping i would die so it would stop. After 2 years or so it seemed to just go away. It then came back right after i smoked a cigarette . Ever since then its been an ongoing struggle. I feel as if i have no control of my life, and im constantly thinking of my breathing. I feel hopeless and feel as if no one understands what im going through or that i have this disease that doctors cant detect. My doctor has put me on xanax for anxiety and it seemed to cut the edge off a lil but its still there. Its not as bad as when i first got it but it still disrupts my life. I can only work 2 days, i don't go to school and i don't have much of a happy life .I've gone to cardiologist, ent's, gi's, pulmonary doctors. I've gone through xrays, PFT, EKG, stress tests, endoscopy . Only thing i have is GERD/LPR with sinsation of lump in throat and a very small irregular heart beat. I also am constantly clearing my throat.I heard that can be because of the Gerd/LPR. I just took a new PFT test and my breathing is normal. i did have a deviated septum but got that fixed..My lung specialist says its just all in my head and that i have this because ive become aware of my breathing pattern. i've used advair, singular and breathing pumps for asthma with no results. when im sitting or laying down its seems to be fine but when i stand up or move it kicks in more. I'm losing hope on what's going on with me. Does anyone have this?If so can anyone recommend anything else i should look for? the only thing i really want to do is a MRI or CT scan but doctors say 99 percent sure nothing will show.Has anyone heard of chronic hyperventilation syndrome? or phrenic nerve damage?cant shortness of breath and gerd be related if anyone can be of help please email me or post a message?
