I had half my thyroid removed December 31, 2013, then they found out it was cancerous, so on January 21, 2014 I had the other half removed. I am taking generic synthroid. I am noticing my feet have a terrible odor, and are soaking wet when I take my shoes off after work, I cannot sleep an entire night long, and I get cramps in my toes that radiate to my feet, is this all normal, and what can I do about it?
