Not sure if I need a new doctor

Hello,

I posted my lab results on this site about 8 months ago and you suggested I have the antibody testing done to test for Hashimoto's.  When the results came back, my thyroid levels were still in the high-normal range, but my antibody test results were high.  244 on the scale 0-33 and low vitamin D I think like a 7.  My doctor still has not given me a diagnosis, but did begin me on synthroid in a small dosage 50mcg.  I am still feel the same as before, including the fact that I have been on a 1000 calorie diet and working out insanely 5 days a week mostly boot camp classes, spin classes and swimming.  I somehow continue to gain weight.  My normal weight is 135, and I have been sitting at 155 to 165 AFTER being on synthoid and still feeling sluggish.  I have been medicated for 4 months now, and the last time my doctor did testing, she only tested my Vitamin D and TSH levels.  My throat has been hurting recently on the left side of my thyroid.  My main concern is that my doctor is not medicating me properly. After reading up on some stuff I am wondering if the weight problem is the T3 to T4 conversion (not sure if it's the other way around).  I don't want to go through the process of changing doctors, and I am not sure if she doesn't know how to treat me.  I think it's Hashimoto's but she has called it unidentified hypothyroidism.  In the past I was hyper, but it was not medically treated.  I am only 26 and trying desperately to get my weight under control now and feel better with a normal nights sleep while I am young and able to control it better.   Please advise, you were right in the past and I find comfort in that.

Sounds like Hashi to me.  
T4 to T3 conversion problems are rare.  Some people benefit from low dose of T3 (5mcg of cytomel 1-2x per day for example).  TSH is still best thyroid test to guide medication dosing.

Make sure vit D is >40.  Would also test calcium...if >10, test PTH for parathyroid problem.
Second opinions are always a good idea if in doubt.

Wow. Someone here (and a valued medical doctor at that) is actually saying that TSH is still the best thyroid test to guide medication dosing. PERIOD.

Doctor, have you seen how ridiculed the TSH test, in general, is here? I realize that FT3 and FT4 tests are useful, but THANK YOU. Many here are dismissing entirely the TSH as a reliable indicator of thyroid condition. I am grateful you set the record straight.
