I was recently tested for several different things because of symptoms that I've been having for awhile. I was tested for thyroid, RA and had an ANA. I'm getting concerned because I have muscle pains, weakness, paresthesia, joint pains and popping, fatigue, dizziness. I was also recently diagnosed with a heart issue called diastolic dysfunction. Which is usually caused by hypertension which I don't have. So we were looking into my symptoms and other causes of this heart problem which is how my doctor came up with these lab tests. My ANA says negative. RA was a 10.5 out of (0.0-13.9) the thyroid tests are in their ranges. So I'm just getting very frustrated.
