High CK levels with Hypothyroidism?

Question

I was diagnosed with hyperthyroidism in June of 2005. I ahd the radioactive Iodine 131 treatment done in October of 2005. They never started me on any meds, for hopes that my thyroid would "kick-start" itself into producing the right amount of hormone. Well, that never happened. I was put on synthroid in Jan 2006 and have been up and down since then. Once they realized I needed meds my levels were: TSH >110.00 (normal 0.50- 6.00) and my Free T4 was <0.1 (normal 0.8- 1.5) and they checked my creatine kinase level which was 585 (normal is 0-165). Does anybody know exactly what your CK level is? Should I push to have more done about it? My levels still arent right, I think now Im getting to much meds. My hair is starting to fall out again and Im feeling sleepy all the time. Before I couldnt move and I got cramps in places I didnt know you could have cramps in. Thats when they realized I was so Hypothyroid. Any serious anwsers, please.

By the way, I am currently taking
200 mcg Synthyroid.

CK is creatin kinase level. It is released into the bloodstream when damage to a muscle occurs. The lab is usually drawn when looking for heart damage. Other types of injuries occur to other muscles. If you had an intense strenous workout causing injury to some muscles this lab could be elevated as well. Lipitor and other statins can also cause an increase in CK. If you are taking these medications, make sure you let your doctor know.
