Iatrogenic: The synthroid (thyroxine) dose needs to be lower based on the numbers. The numbers need to be evaluated by the prescribing doctor.

Thyroid: Your TSH value reflects the hypothalamus message [from the level of free T4 in your blood] to the pituitary gland which tells the thyroid gland how much free T4 to release into the blood stream. Your TSH is on the low side because your Free T4 level is high [normal range .82-1.77]. High TSH means you need more Free T4. Discuss lowering your replacement dose with your physician.

Syntroid raises tsh: If your thyroid was remove "complete/totally" you need hormone replacement. The level has to be determined by your Dr. (Endocrinologist). Do not be your own Dr. YOU NEED THYROID REPLACEMENT NOT AN STIMULANT BECAUSE YOUR THYROID WAS REMOVED.

Possible need: to consider a decrease in levothyroxine if symptoms of hyperthyroidism. Synthroid is suppose to be taking daily early in the morning before meds and meals. Discuss with physician and take medications as recommended

No: Taking more synthroid (thyroxine) will raise your serum T4 levels and by a negative feedback loop cause your TSH levels to decrease(not increase). But if this dose of synthroid (thyroxine) is actually lower than you have recently been taking then yes TSH levels will raise and T4 levels will decrease.
