I am just curious. My mom just told me my youngest cousin has this condition. My question is how likely one could have it undiagnosed through their childhood? Because I just looked up the condition. I see it's pretty prevalent in general population to have the trait. The thing is I have dealt with something unexplainable for years now. I had pneumonia where I had to be hospitalized at 5. But I don't remember anything other than not wearing a coat that day. But I got sick again at 8. The thing is after that point I had a lot and I mean a lot of phlegm in that sickness at 8. But I got better but the phlegm thing hung around. Years later. I always have a lot of phlegm and people always say I have a bad cough. Then added to that I was always more fatigued as a kid. I didn't have a lot of energy. But growth I was ok with early on but it's hard to know because my mother is real small under 5ft can't gain weight ever under 100 lbs. At about 10 and up I had a hard time gaining weight. But like my mother I shot up in weight under 10 and then stopped growing from 10 on. I also had chronic issues with constipation as a young child to the point I had a situation I was so constipated at like 6 I was getting sick. I must say though that has somewhat improved since. Added to this I have found out I am anemic. I regularly would have a level anywhere from low 9 to a low 11. I took also a quantiferon test for tuberculosis and I had to do it over again because it wasn't negative. But second time barely passed as a negative. Which I later was told could mean there was some type of infection I might have with my lungs. On top of all that in the last years I've been getting sick at best every 6 months and when I say sick I mean like I have to lie in a bed for a whole week and can't really even talk because I'm too congested to make much sense. It was also really bad at my old job last year every time I worked there too many days consecutively I got really sick where I had to stay home and not work again. And the sicknesses had similarities to pneumonia. Like I remember at one point it seemed the slightest movement caused phlegm. I had spitting up blood but I have to say on occasion I spit up blood without a nosebleed or anything without being sick in any other way. All this year I have dealt with a lot of hospital visits being told I have signs of sinusitis (sp?) and congestion and then I dealt with also a recent nasal infection. Then I also have had an issue during the holidays usually but that's usually just a cold. I always know it's coming though no matter my environment in mid December been the case for the past 12 years. My question is I haven't told my doctor that I do have a relative with this condition? Or do I leave that out since she's just a cousin? Plus I'm not a child anymore and through some parts of my childhood I only got sick once a year. I even got food poisoned at 9 months with salmonella and I made it through that with medical treatment. At about 8 and after, I had the cough and a congestion issue since. On a normal day I was going to my dr. for a really bad headache last month and she told just by looking at the insides of my nostrils that I was congested. But the thing is that's my norm always has been for years. Also I was at a doctor for an allergic reaction to lactose and they did an x-ray for some silly reason I think she said she did an ultrasound on my stomach and lungs not really sure anymore there was nothing abnormal with my stomach as far they told me. Well should I tell my dr this or not? Do I make yet another appointment or not?
