Need good advice

Hi everyone, I'm 24 (M). I was diagnosed with AS when I was 15. At the time, my doctors prescribed nine tablets plus one steroid tablet every day. I was worried that taking so many medications at such a young age might cause problems in the long run since I had my whole life ahead of me. So I stopped taking them and continued only with Nucoxia 120, because it made me feel normal. With it, I could run, function, and even sleep, as sleeping in one position would otherwise make me very stiff.

I currently take Nucoxia 120 every 2–3 days. Lately, I've been experiencing pain in my right hip (the ball-and-socket joint), along with stiffness in my lower back. I also have pain in the muscles of my mid-back, especially around the floating ribs. It feels like there are tiny needles poking that area.

I just want to live a normal life again. Has anyone experienced something similar or found treatments that helped? Any advice would be greatly appreciated. Thank you.
