After seeing numerous specialists because my rheumatologist felt there was more than just fibromyalgia going on, I am "relieved" to know I have Hashimoto's thyroiditis and am awaiting results of a lip biopsy to confirm sjogren's...the antibody tests for it had come back negative but after my ophthamologist found evidence of severe dry eye and corneal damage to my right eye, and my GI doc found evidence of lack of mucosal lining in esophagus and esophagitis (could just be GERD but also mouth sores and some saliva test showed lack of saliva, too), plus vaginal dryness & abnormal pap with no other explanation, my rheumatologist decided I had enough signs/damage that he thinks i could be one of the 10-15% who don't have the antibodies.
What fascinates me is how many of my labs have been normal, but RIGHT at the cut-offs that are used, such as sed rate. Makes me wonder, if they are ranges, and if some patients don't test positive but have all the symptoms, and others test positive without symptoms, might it make sense sometimes to find the best fit diagnosis and treat that? I guess not, b/c then I might be getting treatment for MS instead of Hashimoto's...even though I tried telling them i didn't have MS but wanted my thyroid checked. Such a frustrating road!
