Shortness of breath a herx?

For those familiar I am on the desbio treatment. I’ve noticed a new symptom maybe I already had it and hadn’t paid much attention but I’ll get a feeling of shortness of breath like I need to take deep breaths in to get more oxygen kinda feeling. I won’t be doing much since I’m not very active usually just relaxing so it’s not me tired.
Not sure if it’s my anxiety or a herx or just a symptom from something else. My anxiety has been kinda bad the past few months. It comes and goes.
Anyone else?

Shortness of breath or air hunger was my worst symptom when I was sick with tick borne illnesses. It can be very scary.

People do mention "air hunger" often associated with Babesia. I think I only experienced air hunger once, after a rife treatment for Babesia.

Shortness of breath can be caused by so many things. Any chance you have iron deficiency? Heart issues? Allergies or mast cell activation syndrome? Reflux irritating the airways and causing the sensation of shortness of breath? Any history of COVID (shortness of breath is a very common symptom of long COVID, and long COVID is extremely common)?

Deconditioning caused some shortness of breath for me. During the years of my illness that I sat/lay around most days due to fatigue, dizziness, and post-exertional malaise, my body became quite deconditioned. Eventually my diaphragm wasn't as strong, and my lungs were not used to taking in full breaths anymore. It was really unsettling! I began doing breathing exercises, restorative yoga, and singing to work on this, and it helped quickly. Once I treated MCAS and did limbic system retraining, I was much more active, and did not experience shortness of breath again.

It can be helpful to use a pulse oximeter and reassure yourself that your blood oxygenation is adequate.
