I am 21 years old male, and since the age of 16 I've been suffering from chronic pain mostly on my neck and back area. Since than I am living a life of pain as it is controlling everything. During these years my biggest preoccupation has been pain, without a break, during the days my brain is constantly focused on my back or neck or shoulder or arm. As I thought the inability of me to focus on something else and chronicity of this problem had made me depressed. I have tried almost everything NSAIDS, corticosteroids, massage, PT, meditation, even some mind-body techniques believing that it was all in my head.I won't continue much of these and will pose my question.
About a month ago I got my blood tested for thyroid hormones for the first time, and it turned out I have an underactive thyroid with FT4 below the range and TSH of 8.4, I went to an endocrinologist, and it has been 2 weeks that I get thyroxine 50mcg for some days and 100mcg after a week. I have my next blood test after 2 weeks, but before, I wonder if all that my pains could be associated with hypothyroidism, and what kind of pain do people with underactive thyroid feel. I also want to know how long does it take for thyroxine to work?
