Almost no lower back mobility all within a month

This all started back in march they gave me some steroids meloxicam and PT which for the first month was going fantastic. However in may when I tried to start working again at my office job and everything came back. The sciatica the back pain and now I have almost no lower back mobility. I had to switch PTs around the same time because me and my ex girlfriend didn’t work out and I definitely contribute that to everything. I’m so burnt out in trying to figure this out I have a rheumatologists finally who suspects ankylosing spondylitis, but we haven’t gotten an mri yet I’m going to my doctor today to ask about an ortho consult. I’ve been having erectile dysfunction too(22m) for the past month. This condition has taken almost everything I’m just looking for any advice on forward steps or anything that has helped anyone. Thank you
