Underactive Thyroid
"I have been on Levothyroxine for 2 months and was switched to Synthroid for another 2 months.  I know it hasn&#039;t been long but it is driving my body crazy.  Here&#039;s how:  The Levothyroxine made my hands and feet swell badly so my doctor suggested switching to brand Synthroid well now my face and jaws are swelling.   I went to the emergency room they did a CT Scan and said it was swelling in my tissue. But my doctor is insisting the medicine is not the cause and to stay on it.  "
