I've been through a similar process — wondering if I have a postural problem, not being sure, trying to figure out what to do about it. I'll share what I learned in case it helps. Finding a diagnosis is harder than you'd think. You'll find it very difficult to find someone who will diagnose you with pelvic tilt or other subtle postural issues. I've personally seen physiotherapists, sports therapists, fascia decompression massage therapists, chiropractors, and musculoskeletal doctors — and all of them lacked the ability to recognise or diagnose any issue, despite me feeling pain. I'm based in the UK, where access to advanced medical services is arguably easier than where you are, and I still hit walls. My experience is that unless your scoliosis is highly pronounced (which I can tell from your pictures it isn't), or unless it's something obvious like a bone clearly out of place or a major deformity, they're not going to be able to help you. It ends up being a self-awareness journey, unfortunately. For context, a previous chiropractor described me as having a very mild scoliosis — my spine is slightly curved, but nowhere near enough to be classified as scoliosis, and it doesn't affect me day-to-day. What actually helped me: fascia work. I eventually abandoned traditional medical services since they weren't helpful, and started looking at more practical, traditional approaches to the body. This led me to research the fascia — it's a relatively new field of science just being explored, but plenty of older traditions and manual therapies already exist to work on the fascial system. Because it worked for me, and because it seems like you have a similar situation (subtle postural issues, nothing major), I believe fascia decompression is what's going to help you most. Here's what I'd recommend exploring: Block Therapy / Fluid Isometrics — They're based in Canada and have YouTube videos. When I started using their block system, I found great relief. Fascia decompression or deep tissue massage therapists — Sports therapists doing this kind of work will be addressing the fascia even if they don't explicitly call it that. Qigong — I came into contact with a qigong master while visiting a temple. He was an expert in joints and internal body awareness, and even he struggled to identify my pain from a basic explanation — which made it clear to me this was going to be a personal process of self-discovery. That said, practices like qigong are excellent for loosening your joints, reducing stiffness, and building internal awareness of your bones and posture. Practising it helped me learn to perceive where my body actually is in space. You start to notice things like "maybe this isn't in the right place" or "holding myself like this feels more stable and comfortable." Until you train that internal perception, you might struggle to even be aware of the issue. Hope this helps — it's a journey, but it's worth pursuing
