Yes it looks like you have damage your back further, my suggestion is check with your doctor either ortho or physio and then do take mri scan if your doctor also recommend. But one more thing you can try at home is just take rest keep doing heat foamentation and post that apply a good pain releiving ointment. And correct your posture for sitting standing and walking activity. Most important thing when u go for mri do compare it with your previous mri report. And then if every thing is fine I suggest you should follow a good spinal exercise program. Which can strengthen your spinal muscles so that the muscles ability to take load can be improved next time. But of course it's not suggested to lift heavy wait at least for next few weeks. Do consult a good physio for back strengthening exercise. Take care....
