What is causing back pain in me?

Hello doctor,

I have recently been experiencing lower back problems on the right side of my back. I work out a lot and have been working out for some time now and I generally do a range of heavy to mid-weight sets quite often. I remember initially feeling this pain immensely while squatting (was wearing a belt). Which I thought was just a muscle strain so I reverted to doing other back exercises that day. After leaving the gym, I remember the pain and soreness (I would say more soreness than pain) persisting for about a day and did not feel anything after.

However, recently, I was walking and somewhat slipped on some ice. I never fell, but because of the sudden jerk, I felt that pain in my lower back on the right side immensely once again. This pain generally always comes and goes and it is usually during back exercise or sudden jerks. Therefore, I was wondering if in your opinion do you think this would be a problem regarding a strain of a muscle or a disc problem in my lower spine. If so, should I have an X-ray done to confirm?
