<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi i have been told that i have thyroid issues and lately my arms and hands fall asleep while I am sleeping...  <response>: Hi Rosemary, welcome to Chat Doctor, Please check your thyroid hormones levels... i.e.: blood tests for T3, T4, TSH. Also, please have an ultrasound scan of your thyroid. These are routine tests and can pinpoint any trouble with the thyroid. Please get back to me after these tests are done. Also consult a good endocrinologist in your area. See this site for more on thyroid diseases: and take care, Chat Doctor.
