Since the middle of August I have been experiencing shortness of breath, I went to the Dr. and she said I had a sinus infection after two different antibiotics I still didn't feel any better. I did seem to have some relief for a week or two and now my problems are getting worse, I have a lumpy feeling in my throat when I swallow and now my throat just below my chin feels extremely tight and swollen, I have pressure in my head and my face feels like it is throbbing I'm on Zyrtec,Rhinocort,Flovent and Maxair inhalers they are not helping any .I am going for a pulminary function test tomorrow and they wont test me for allergies until we get the results from that. Could I have developed an allergy all of a sudden to my dog? I have had him for over 2 years and have had dogs all my life and never any problems. I do smoke and am fighting with quitting as I type this, I am so depressed over this everyone thinks I'm full of it and I feel that there is something terribly wrong. Does anyone know if the tightness could be from the dog, It actually seems to get worse after I leave the house and sleeping isn't a problem. I'm getting desperate.
