Finally got my call back from the doctor's office (...they tried multiple times but apparently my phone doesn't do vibrate any more. Greeeeeeat.)
It's looking very much like all those times I complained about joint pain and whatnot, and everyone around me basically told me "shut up and stop being overdramatic, it can't be arthritis you're too young for that", I wasn't being overdramatic~
Getting a referral to a specialist at some point in the next [time period] so they can figure out the exact details; and they've got to go drilling for oil blood to check for telltale signs first.
God, this is making me happy to actually have some sort of confirmation that something is wrong and figuring out some sort of pathway to fixing it.
