Hi Kathy, I hear your concerns . If I remember rightly Kevin works long 12 hour shifts ? I'm not really suprised that he is so tired when he comes home. It's a good opportunity to catch up on sleep and rest and recover , ready for the next stint. I'm guessing that he has had his thyroid functions measured since starting on thyroid replacements?
Kris is nearly 3 years post surgery and does still have a catch up nap about 3 times a week. As part of his continued surveillance I do check his blood work including a Full Blood Count, Thyroid Function and Biochem at least 3 monthly. I guess you have already had it all checked?
Here in New Zealand, no one gets regular scans. Kris has not had any scans since preop. He has 3 monthly checks and scopes with his ENT which in my opinion, is a great checkout. Remember most cancers are found by the patient , not scans. Also there has been research which shows no improved outcomes from regular scanning versus no scanning.
Keeping you and Kevin both in my thoughts,
Tammy
