I have SOB,a cough which sounds like a dog barking and post nasal drip and constant lower back pain on exertion. Have had CScans done(only showed a 1.6 cm nodule on my thyroid) stress test, many blood tests and now booked to see a respiroloist as I am also extremely short of breast on exertion. Also having PF test in Feb. I am usually a very active person but for the past 6 months have done very little. I also have been diagnosed with Intermediate Uveitis(2 years ago) and have gone through many test as 50% of the time it is caused by something else happening in your body,ie Sarcoidosis, lupis , MS, a tumor, etc. Any answers you can give me would be appreciated or any suggestion ...
