I ask I'm almost 1half month done my thyroid surgery why it's still I fell my neck is to tired thank u?

There will be. A NORMAL "thickening" at the site of your surgery for several months after the procedure! In addition any fatigue you had prior to the surgery I assume will respond to thyroid replacement (if indicated) or a little "tincture of time"! Hope this helps! BE WELL! Dr Z.
It depends. It depends on what you mean by feeling tired. If you mean an aching or stained neck after exercise or a car accident, that is probably from positioning in the operating room and will resolve in 6 weeks, more or less. That time could be shortened with a NSAID.
