Whats your thoughts on these TSH and FT4 test results and the following symptoms

[Djw211]

Hello Everyone,

I am a 32 male, 5'10, 205lbs. I work out 5-6 times a week and eat on the healthier side. As far back as I can remember I get hot extremely easily and sweat profusely on my forehead, middle of my chest, and middle of my back. The heat seems to come in almost a wave, and I can feel it rising until it reaches my head(hope this description makes sense), and I can never seem to cool down. An odd part about this is, on occasion, my feet will be extremely cold at the same time. If I'm not wearing socks or shoes my feet will be almost painful, they're that cold. My doctor said I have hyperhydrosis and prescribed me oxybutynin. This does help curb the sweating. I'm not sure I have hyperhydrosis because I only sweat when I feel hot, it's more like my body's thermometer is off, so I had my thyroid checked out. The results are as follows.

TSH-4.72  mcIntl_unit/mL  Clinic range 0.27-4.2
free T4 - 1.11ng/dL   Clinic range 0.93-1.70

My doctor said even though the TSH results are high the FT4 are normal and there is nothing to worry about. With that being said, I still get extremely hot easily(I literally feel like I've run a few miles), cold feet, extreme tiredness, dry skin, extreme thirst, trouble falling asleep. There's also been days and strings of days where I feel good. There was a three week period where I felt really good(no excessive heat, felt energetic, etc. I stopped taking the oxybutynin to see how my body would respond because I always suspected I did not have hyperhydrosis and I did not excessively sweat or feel overheated. Any advice or direction would be extremely appreciated. I hate living like this.

Testing TSH is the general practice in diagnosing for hypothyroidism.  If TSH is above about 10 it is called overt hypothyroidism and treated.  If the TSH is above the range limit, but less than 10 it is called subclinical hypothyroidism and the patient is typically told there is no thyroid problem and symptoms must be due to something else.  This practice is erroneous.  Symptoms should be the mot important diagnostic, followed by additional tests for both Free T4, Free T3, antibodies related to Hashimoto's Thyroiditis, and others.  You can read about this in the following link.  I highly recommend reading at least the first two pages and more if you want a better understanding of why your evaluation was inadequate, and what should be done.  After you do some reading I am sure you will have additional questions which we will be glad to try and answer.
