I have been on levothyroxine for at least ten years or more I was seeing a physician assistant at a local clinic he put me on these meds due to having symptoms and although my levels were on the low end they were not quite abnormal ... put me on this med then I decided to switch to an actual Dr several years ago but neither referred me to an endo I'm now on 75mcg and 88mcg alternating daily. I lately have been feeling dizzy, heart racing on occasion, nauseated and very disconnected could I be getting too much meds? My Dr (family) says there is no reason to test any level but my tsh because I'm hypo not hyper... feeling very discouraged
