I have had several blood tests done and the only thing showing up is the TPO level being 134 in a range of 0-34. I have MRI and MRA's and nothing showing up. I have also had a thyroid ultrasound and they say there is a thickening of the thyroid. I have all these symtoms that do not go away. It all started with muscle pain and weakness of the legs, now I have alot going on in the neck. I have alot of throbbing pain, trouble breathing sometimes, some pain that goes down into the chest and upper back on the right side, ear pain on both sides off and on. These pain symtoms usually happen once or twice a day lasting anywhere from a few minutes to an hour or more. I am only 37 feel like I am much older. I am so frustrated and I just want an answer to what I have. The pain in my neck is getting so bad at times, it scares me. Please, if someone can help, please do.
