80% better the next day

The story

I had a slipped disc or something. I could barely walk and it was my vacation. It was my lower back, it was hurting me like hell when I was sitting down and standing up. I told myself that my back is all right, that I can walk normally. I was 80% better next day.

My partner had the same issue last year and he had to exercise 3x a day for like a month or so, take meds, have mri... My symptoms were basically the same.
