How were you diagnosed? Anyone undergone a biopsy?

All of the classic symptoms were there, but confirmations came from bloodwork. Has anyone undergond a biopsy of the lip or salivary glands? They can also diagnise by determining enlargement of the salivary glands.

I hope no one had to go through the biopsy! Especially of a gland!
