On thyroid medication for years. normal tsh and free t3 but last two exam, high free t4 (1.8 then 1.87) normal values 0.8 to 1.77. what could cause it and could that cause increased palpitations. also pain in the neck as well for a week?

If the TSH level were also trending down to the lower limit in the last 2 checks, dose of levothyroxine should be reduced because palpitation could be an early symptom of mild, iatrogenic hyperthyroidism. Your neck pain is likely unrelated.
