If you are not already diagnosed and treated, TSH 4.11 is not considered hypo.
Per AACE 2006 amended guidelines, the US Government 2004 Guidelines and UK 2006 Guidelines
"TSH of 4.5 to 10: No routine levothyroxine treatment for patients with TSH levels between 4.5 and 10 mIU/L, but thyroid function tests should be repeated at 6- to 12-month intervals to monitor for improvement or worsening in TSH level. Early levothyroxine therapy does not alter the natural history of the disease,.........
TSH Higher Than 10 mIU/L Hypothyroidism Levothyroxine therapy is reasonable.
Data do not confirm clear-cut benefits for early therapy compared with treatment when symptoms or overt hypothyroidism develop."
Your other issues I can not comment on.
If you haven't already, you might go to the doctor thyroid forum and ask Dr. Lupo at
