coughing fits while in the water

[steffie583]

So here is my confused question... lately when i go in the pool i get into these horrible hacking fits where it sounds as if i have ridiculous bronchitus (bronchitis)... however out of the water i dont cough or feel bad at all.... I'm not swimming or exerting myself in the water just cooling off, i have even tested this by not going under water at all so i know i'm not taking in any water.. so my question is when i submerge my chest in the water and my result is a deep lunged coughing fit is this a sign that something is wrong with my lungs? I recently had some x-rays done because sometimes when i lay in bed at a certain angle its a sharp pain when i breathe in and the doctor said that my lungs were "good" so can an x-ray really show my dr. what is going on in my lungs- and is there even cause for worry over this? Maybe i might understand the coughing in the water if i were like swimming laps or something and swallowing a lot of water but all i have to do is have my chest submerged in the water for a few minutes and the horrible coughing insists... Does anyone know any helpful information that can help me here?!
