Get your thyroglobulin (Tg) checked asap. Sudden increase in TSH while being on stable meds, combined with an increase in Tg could indicate a recurrence.
Before messing with the meds, get your levels checked and *insist* on Tg.

Do you take a brand name replacement such as Synthroid or Levothroid? If you take a generic, your pharmacy can switch generic brands and all generics aren't alike. If you do take a generic, you may want to get your doctor to prescribe a brand name so your dose will remain consistent.
If you do take a brand name, another possibility for requiring a dose change is recent weight gain or loss.
Good luck to you!
