Heard a pop or crack in my elbow

Hey guys! Has anyone ever had this before? I had been poling for nearly 2 hours so I was tired but not exhausted, and decided to just finish with an elbow grip hold, so I went up and got feet off and did a straight edge, and then put legs out into a V and had to steady my balance with my core (my weight shifted on my arm a bit) and my elbow in my lower arm made a pop/crack sound! I came straight down and expected a really bad injury and expected pain but had neither! Now if I press down on my palm on the desk in front of me in a particular way the elbow hurts a little but thats all.  I can still invert and feel minimal pain if that.  Did I hyperextend it??? I ordered an elbow brace off ebay right away, maybe wearing a brace on that lower arm will help the elbow feel more stable.  My wrist braces help my wrists!
