This is Dr. David
I am a cancer doctor.
the taste of blood you are having most likely is not from your history of papillary thyroid cancer. it is more likely due to gingivitis inflammation of the gums in your mouth or from bad acid reflux or sinus infection. do you have bad teeth? when was the last time you saw a dentist to be checked for gingivitis. gums tend to bleed very easily when you have gingivitis.
that 14 mm lymph node most likely is a reactive lymph node and not due to your papillary thyroid cancer. the prior radioactive iodine should have killed any thyroid cancer in your body.
ask your doctor for an thyroglobulin blood test which can be elevated in patients who have thyroid cancer.
your doctors should also be giving you thyroid hormone pills to help suppress your TSH levels down to below 1.0 range. this can help suppress any potential thyroid cancer cells in your body. what is your most recent TSH blood level.
let me know if you have other questions.
