Dealing with Irregular Breathing Disorder after COVID

I had a CAT scan of both lungs to make sure there were no infiltrations. I was clear. But you may want to have that done

For me I’m suffering with recurrent chest infections palpitations so they have diagnosed long covid now checks on my heart was all normal no damage .

For me my body is hyperventilating over and over, then under my bust swells and bruises. I have no idea how to relieve it and they doctors don't think an inhaler will help x
