I was diagnosed with Hashimotos disease in October of 2011. I had an ultrasound and they found a complex bleeding cyst on my thyroid. The biopsy was performed and it was benign. Ever since the biopsy I have been swollen in my collarbone area. I also have some chest pressure. I have been on levothyrone (100mg) once a day. Anyone else ever experienced any of this? Anything would be a help!! Please!
