I discovered a lump in my neck about 2-3 months ago. I had a sore throat at the time so I didn’t think much about it. I am concerned now because the lump is still there and has grown. I believe the lump is where my tyhroid is located. Has anyone here ever experienced an enlarged thyroid, and if so what was the cause? I am going to the doctor in the morning, but would like to hear from others also. I have also been experienceing the shakes, intolerence to all temperatures...either very hot, or very cold. Also kinda short of breath at times, like it may be constricting my airway....Any thoughts?
