I have sharp low back pain after weight lifting and it hurts while lying down. Please help.

Hello doctor,

About six months ago, I developed pain in my lower back mainly in my waistline towards the right side. I visited a doctor and we tried PT but it did not work. I then scheduled an appointment with a chiropractor, however, it was canceled dude to COVID-19. A couple of days ago, I was lifting at the gym and everything was going fine. I started noticing the left side of my back waistline beginning to hurt so I went home. Since then, the pain has worsened a lot. It is a sharp shooting pain that will extend from my waistline into my buttocks. I can barely sleep at night because when I try to turn over the pain is too extreme. I feel it a lot when walking as well, or trying to stand up if I am sitting down. Also, lying on my back causes the area to ache really bad. The pain is at its worse when I need to roll over in bed or when I stand up from being in a lying position, even if I was lying or lounging for a minute or less.

I am a 23-year-old male in the military. The initial back pain that started months ago was found to be caused by wearing my sidearm at work for 9-13 hours a day and additional gear such as body armor. However, this new pain is something different. Please help.
