Ths level is 0.79 and free t4 is 18.2. symptoms include: palpitations, constipation, migraines, pins and needles and lethargy. is my thyroid to blame?

Thyroid: The free T4 doesn't sound correct. I would check or repeat this but also add ft3 (liothyronine) and reverse t3 (liothyronine). Your symptoms currently don't necessary go all with thyroid. There could be many other reasons for your symptoms so other blood testing will be needed to rule out other causes.

Likely: If your TSH is low - suppressed, that is because your thyroid is "over"-functioning which is hyperthyroidism. The symptoms you describe can all be related to an abnormally functioning thyroid gland. See an endocrinologist for further workup to determine the cause of the overactive thyroid.
