Dx with infolding of arytenoids upon inhalation. Worsening Winded/wheezing. Could this be related to undifferentiated connective disease?

Unrelated . To my knowledge, your 3 problems (infolded arytenoids, worsening shortness of breath - assuming you have no stridor which is throat sounds on breathing, & connective tissue disease) are unrelated. Keep your followup appointments, take your meds as directed, & report any changes to your clinician. Also note other physicians' responses to your question: may have more experience w this than I. .
