I'm a 28-year-old woman and for the last couple of months, I've been having some trouble with my breathing off and on. My ECG came back normal, but my RBCs were a bit low at 9.8. I saw a doctor and they gave me antiallergic meds, but they haven't really helped. I'm thinking it might be something to do with allergies because the issue started around wheat harvesting season. There's no wheezing or any sleep discomfort, but it does feel like my deep breaths get interrupted. Can allergies last this long? I'm not having any fever or throat pain, and my tonsils seem fine. Could this breathing trouble be linked to PNS? How can I find out if allergies are the real cause? This is the only health problem I'm dealing with right now.
