10 months ago I started having difficulty breathing, mucus in my throat that has effected my voice, sore red irratated throat and vocal cords. I also have a sensation of something in my throat and a feeling of constriction in my throat as well as stiffness. I'm constantly swallowing. I can occasionally spit out some mucus from my throat. I've been seeing an ent specialist and he initially thought it may be reflux. I've been extensively tested for this and it is not reflux. I've had a barium swallow, monometry, lung x-ray, sinus and throat ct scan all with normal indications.
The only change in our family prior to my first symptom was our family got a puppy. We kept the dog until two months ago and sent her to my inlaws thinking I may be alergic. We extensively cleaned and got rid of our carpets. Within a week my symptoms slightly improved and have since leveled off. I went to an allergist and found I was alergic to dust but not animal dander. However i've always had difficulty with cats and animals with fluffy hair.
The only other issue I can add is I went out of the country 3 times just prior to these symptoms. Three months prior I went to equador. Two months prior I went to germany and the month prior I went to turkey. I spent about 3 weeks at each location. I'm out of ideas. My ent wants to test me for cough varient asthma? I've always been a runner and never had problems with my breathing. Prior to this i've never been sick i've always been very healthy. This problem is affecting my job. Any information would be greatly appreciated. Thank you
