Im going to the doctor this week to try and get a recommendation for a cf sweat test. Im worried they may think Im crazy, but I'm so frustrated that I dont know what else to do. Since a child I have been getting sinus infections and bronchitis frequently. My doctor diagnosed me with asthma and put me on antibiotics and that worked for a while. I'm now 22 years old (female) and have started going downhill since 16. I know cystic fibrosis is usually diagnosed as a child but i was not tested at birth and I have read that some milder mutations do not.become severe until later in life. Anyway at 16 I started having severe pain in the area of my gallbladder and had to undergo a few scans and a colonoscopy/ endoscopy. They diagnosed me with ibs. Which does not fit because I do not have those symptoms all the time. I am 5'5" and my average weight used to be around 130. In the past two years, despite how much I eat, I keep losing weight and I now weigh 108 pounds. The number of sinus infections that turn into bronchitis increased as well. Now the longest I can go without being sick is two months. Like a clock. And it is.much more severe, requiring stronger antibiotics and a nebulizer and now large doses of prednisone every time because my chest and airways get so swollen I feel as if my chest would tear with one more cough. It is so painful I cry, and have almost passed out. What makes me angry is that no doctor has ever asked WHY I keep getting sick. They just treat my symptoms. This cant be normal. Its at the point where it is depressing, Im so weak all the time. Am I doing the right thing? I am also french canadian,lithuanian, and cicilian..second generation America which I read Cf is prevelant among those ethnicities.
