Re: Intolerance to cold
Have your doctors run any tests such as a lumbar puncture or done MRI's? Have they checked your blood work? I would be hesitant to just treat the pain without knowing the cause.
Being cold can be a sign of hypothyroidism, as can weakness. Have your thyroid hormones been checked? You might want to try an internist instead of a neurologist in case your symptoms aren't caused by a neurological disorder.
I hope you find some answers.
