Injured my lower back a year ago. I thought it healed up 3 months after but found out there was something wrong .It would be stiff and would take a longer time than usual to warm it up. I even spar, do my training well. But it would just stiffen up sometimes. So I got a session David and I swear the pain just went away! It just loosen up! I also became more mobile in my sparring and training! So if you guys feel something “off” or if it’s just something “small”, make sure to get it checked because it can get BIG in the future.
