Joint pain this early?

I'm around 6+2 or so, and I've had a dull ache in my right shoulder that's consistently worsened over the past week. Anyone else dealing with joint pain? I had assumed it was coincidental and not pregnancy-related, but it seems every little physical change I notice turns out to be a symptom I never knew about! For some reason I was under the impression relaxin isn't released until later in pregnancy, but googling suggests otherwise.

So any successful remedies? Does Tylenol help? Heat? Massage? It's worst while sitting at my desk at work, using the mouse and keyboard. Not comfortable at night either. I'm just hoping it doesn't get too much worse in my shoulder or show up elsewhere!
