Thanks for the post, very very helpful.
I am hypothyroid without my meds.
I have had genetic testing by 23andme.com for $99 (best $99 you can spend) I will be looking for the P450 CD6 enzyme. I do have a gene (rs6269 AA) that means i have increased pain sensitivity.
I have no relief with nerve blocks of C4-C7, still pain in the shoulders while sleeping.

thanks again.
