Bone & Muscle problems

I was depressed about something and doing some work. Suddenly got a sharp pain in the left side of my lower back. I immediately sat down. But the pain and discomfort kept increasing and there was a point I couldn't sit properly and needed support to stand. Went to local doc, I'm better now. But still have trouble in bending and sitting and getting up. Feel some nerve issue. What is this and y a sudden pain ? Give anyone pleas explain

When I move my neck upward, I can't hold my position for long as I started shaking & frontal head becomes heavy. Sometimes internal shaking also. Also, when I keep my head down for a long time, same thing happens with vision problem.

I was stretching out my hip flexors cuz of tightness with the help of my feet and I cranked it bit too hard which induced my acl grade 1 sprain. Initially it was stiff for a week then it got fine but after few weeks instability crept in and my knee felt wobbly as if my lower limb would just separate out. So my current condition after 10 mnths  is such that there is no pain no swelling but instability is worse on my right leg. But it doesnt buckle but definitely can't turn around or walk sideways just walking in straight path and stairs is fine. What to do in such case I'm just trying cycling out as physio for my quads, hamstrings, calf, glutes those muscles feel a bit weak. How would I recover completely as I was before as this issue bothering me a lot and I can't be at my 100 percent and feel low on confidence whenever I step out. Because of this issue my hips, my back, my neck everything is getting compensated. Share your advices Asap. I have attached my mri do check it out. Thanks.
