i feel ya' on the second guessing part.
Same thing happened to me some years ago with my lower back.
For me, it was a bit of a mind fuck.
Couldn't go nearly as heavy on pretty much every lift and started getting worried about losing strength and size.
An extra rest day and lighter weight made all the difference. Just had to listen to what my body was saying and ignore my ego.
Best bet would be, go with a lighter weight until you're healed up, then gradually add more weight little by little until you get back to where you were.
Stretching/warming up with even just the weight of the empty barbell has always treated me good too.
Minus some slight elbow soreness, i've been injury free for years... knock on wood.
