Approx 5 years ago, my husband completely 'stopped' sweating on his right leg. Since then, slowly he has stopped sweating COMPLETELY on the right side & just recently his head down to his left nipple. Basically, he sweats NOWHERE except the left side of his body from his nipple down, and the sweat pours offf of him just saturating his clothing. We had him to an Endocrynologist who scratched her head, said she never heard of such a thing & then took a stab in the dark ordering thyroid bloodwork (which he had just had done by our family physician, & showed ZERO red flags) & a scan of his thyroid. I was not comfortable with the direction she was taking. I cancelled tests she ordered & headed to a different Endocrynolgist for a 2nd opinion. He did not believe this was thyroid related givesn the initial blood test results that were done. He, instead, ordered a different set of blood tests that are based on the fact that my husband has been in the Nuclear power industry for 30+ years. However, he is leaning toward having to possibly send him to neuro, feeling like the cause is 'multiple tumors' in his back. Currently we are awaiting the Lab tests & 24 hr peeing in a bottle test to come back. In the meantime we are wondering what this 'multiple tumors' in his back means, IF that is what is causing this issue. Whatever is causing this surely needs corrected. The wait, wonder & lack of knowledge is causing much loss of sleep.
