Thank you Colleen for the response and for this resource, which is a wonderful connection! To respond; we have discussed the possibility that this is Covid recovery related. I have not been able to determine what makes it better or worse yet. I had thought the humidity or activity might be a trigger but I seem to have the symptoms as the weather has returned to dry and on days when I am relatively sedentary. I do have an inhaler that I can use but generally don’t because it makes me quite jittery.
