Hi...thanks for reading! I have been having unexplained symptoms for almost a year and half now and I often think I may have a thyroid disorder. Specifically hypo. I have had my thyroid tested twice but after reviewing the results I see I was only tested for TSH with relflex to free T4. My level was 3.13 which is normal. My question is how important is the free T3 test? I see people talking about it but I haven't had that one. Should they have done that test as well and does anyone know why both times they would have left that out? My symptoms are tingling, burning, numbness off and on in extremities, brain fog, weakness in legs and arms, intolerance to cold, dry scalp, dry and itchy eyes with bouts of blurry vision, muscle twitching, fatigue, mood swings, forgetfulness, trouble concentrating, inability to loss weight after dieting and exercising. I have been tested for almost everything so I'm pretty much losing my mind now. I have no motivation to do anything ever but just keep pushing forward because I need to work to support my son. Please help!
