Hi, I am really new to this site but I saw your post and felt the need to respond. I also deal with air hunger on a pretty regular basis- I often say that it feels like my lungs are too small or that I just can't get enough oxygen! The severity varies. This symptom, air hunger, was a clear indicator of having an infection with Babesia, which is a coinfection of Lyme Disease. Have you done any research into Lyme disease and its co-infections? It might be worth a shot to see a Lyme-Literate doctor (LLMD) in your area if this air hunger persists. Babesia is a coinfection of Lyme, and one can become infected with Lyme (or babesia or the other coinfections) without knowing or having the bulls eye rash. The issue with this infection in general is that it is very difficult to get an accurate test done, which is why seeing an LLMD is SO important.
