Can't Get Under a Bar to Squat

Hi all been training on and off for around 15 years now, last time I squatted (low bar) as I tried to get out from under the bar after racking it, I heard a pop in my right elbow, it hurt a little but hasn’t hurt since or stopped me doing anything until the next week I tried to get under the bar again and I can’t physically do it, when trying to get in position it causes bad pain down in the tip of my elbow (inside).
I’ll train around it but just curious to hear from anyone with similar experience .
Peace

Sounds like you have some nerve impingement and tightness and restrictions in certain areas. Id try looking at some rehab therapies and releasing of any adhesions in the area.
