Hi. Thank You. I Have Been Diagnosed With Undifferentiated Connective

Hi. Thank you. I have been diagnosed with undifferentiated connective tissue disease and now having trouble with my tongue. It started three months ago and now is swollen to twice it's size and I have a tender neck and sore throat. I received an Epi injection and my tongue did not go down in size. I want to find out if Hashimotos Thiroiditis could cause this problem.
