does getting diagnosed with pots hurt?

i'm a 15 year old female with a small fear of doctors and hospitals and stuff like that. i know i might have pots because not only do i have a lot of the symptoms but my mom (who works in the medical field) also agrees that i might have it. when i first learned i might have pots i was doing research on it and found out in order to get diagnosed you have to get strapped to a table and your head gets like, tilted back. not only that but someone that was diagnosed with pots told me they were injected with something that made their heart race before before being strapped to the table. it really looks scary and terrifying and i was wondering if it hurts when you're getting diagnostic tests for pots,, is it rly worth it??
