Following up on DavidCPA's post. My advice is to schedule an appointment with an endocrinologist, preferably one who went to medical school in the 21st century. While many GPs and oncologists feel comfortable treating thyroid issues, they often rely upon outdated lab test references since the TSH is just a simple blood test. You want the TSH level to be the same now as before cancer.
What is your husband's TSH level now? If you don't know what it was, it should NOT be higher than 3 even though the lab results say up to 4.5 is okay. But that is contrary to all the specialists. Before cancer I was 1.6. After TX it had shot up to 4.3. With Levoxyl pills, it gradually went down to 3.04, then to 2.17 and then 1.48 and now 1.36.
If his fatigue is related to thyroid, then time will not make it better only worse, unlike the other symptoms.
As for the thick mucous, seltzer water (in the small cans, not the big bottles or else the Fizz is lost) as a rinse really helped me spit it all out without choking. I went thru a six pack a day of generic store brand selzter water. Be sure not to buy tonic water or mixer as that has quinine in it which burned my mouth the one time I grabbed the wrong six pack.
