Hello,
I do gymnastics and I train everyday, I do cartwheels, round-offs, front limbers, back walkovers, and back bends.
Lately I have been experiencing pain in my lower back, and it started to hurt when I get up from the back bend.
Today I woke up with a bump in my lower back, and it hurts, and I can't get up properly from a back bend as it hurts.
What is that bump??
