Hi,
I had a lump on the left side back of my neck which was examined twice via ultrasound and deemed to be likely a cyst. it is now one year after those ultrasounds and the lump is gone, but the muscle/tendon next to it on the back left side hurts at a level 8-9 whenever it is stretched slightly or touched. My doctor keeps saying it is nothing to worry about. I am a cancer survivor and so far thyroid tests and blood tests are in normal range. Doctor does not seem to be concerned about the pain.
