I went through the radation Iodine take up test almost a month now and had a biopsy done about two weeks ago. This was really painful. The doctor said because of a short neck and the nodules being low and far back that they were hard to get at. Every since I have had alot of pain in neck and slight headaches, just feeling like I have been run over by a mack truck. Also I have been on methimazoid 3 times a day now for about a week, What are the chances I will still need the iodine treatments or surgery? Has any one else gone through the whole nine yards and been this sore from a biopsy?
