Okay guys, so I have been having some dull pains in my pelvis for the past 3 days or so, it stays for about an hour or 2 then leaves, it's not super bad pain, but it is very annoying, especially when I try to sleep; I have to sleep on my side or stomach. This morning, I was stuck in bed because It felt like my leg and knees would pop out of place if I tried walking

but not really. its hard to describe.
what's the deal?
Has this ever happened to any of you?
