since 1994 i went to the emergency room because i got a severe pain under my heart and over.They admitted me because they said my oxygen was low they tested me for every test known to man and said that maybe it was a touch of broncitis.I went to follow up clinic because i felt worse though i had no cough , but still nothing.months passed and I could feel a cracking coming up my chest it started from like my lower sternum and I would feel my chest gettting tighter and my breathing was worse and worse. also my throat was so dry I had to sleep with a cough drop in my mouth.now 2009 still no diagnosis my breathing is to the point were I cant sleep at night i cant run,at rest it is so hard to breath ,and now other symptoms have developed,lots of pain on sides of neck blurred vision, vertigo, head feels full ears ringing, etc . I wonder if anyone out there has anything similar to what I have . I am to the point that i have not seen a doctor in years ,I have lost my faith in the medical proffesion.
