I am a 29 year old, healthy, active, happy man. I just recieved my blood screening results from a voluntary test and am nervous about the results. My 'TSH, 3rd generation score is 19.5, says normal is .4-4.5. My throat has felt a little swollen lately when I swallow. I have been under alot of stress and unhealthy lifestyle for the last few months... cramming for tests...ect. Could a summer away from stress and a healthy lifesyle reverse my TSH score? Do I need to worry? Thank you!
