A little over a month ago, I started developing some strange symptoms. It started with just a cough, so I took some OTC cough meds for several days which did nothing. After that I went to my GP who prescribed some antibiotics, which also did nothing. My symptoms started getting worse after a week or two, to where I was having a hard time breathing and had a strange feeling in my lungs. It's kind of hard to explain, but it's sort of like I'm hyperaware of my lungs in my chest, like I can actively feel them sort of like when you stretch a muscle. After a night of having such difficulty breathing that I considered going to the emergency room, I returned to my GP. I have a history of mild asthma, so he originally attributed my symptoms to an asthma flare although I've never had symptoms last longer than a day and never this severe. He gave me several medications, and had me do nebulizer treatments every six hours for about a week which was always very effective for my asthma. At this appointment he also checked my blood oxygen percentage, which was slightly low(I want to say 95 but I can't remember). When I still didn't respond to any of this and my symptoms continued to worsen, he had me have an x-ray of my lungs. Much to my surprise, the x-ray came back totally normal. GP prescribed yet another medication, and I haven't responded to that one either. I feel like the symptoms have started to get exponentially worse, to the point that I'm coughing and sort of gasping for air for much of the day. A couple times I coughed up small amounts of blood, but not enough that I felt compelled to go to the hospital. Other than that, it's a dry cough.
I do have a history of weak lungs, to the point that when I'd do peak flows the techs would flat out tell me they didn't believe I was actually taking a deep breath even though I was to the best of my ability. However, I've never had symptoms like this, especially that last so long or been nearly this severe. It's to the point that my GPs basically have no idea what's wrong with me, and I'm honestly starting to get kind of scared. I've dealt with other strange symptoms that took years to diagnose(temporal lobe epilepsy), but at this rate I need to get some sort of answers asap. It's gone from a mild cough to practically choking, and my lungs just feel sore like an overworked muscle. Searching these symptoms online brings up lung cancer websites and such, but since the x-ray was normal I really don't know what to think.
