Yep, definitely struggling to walk is tough.

I have gotten relief, but my physical therapy is more functional--their practice has a more "active" approach that is based more on "what you can do," as opposed to "what is done to you," so they rarely use ultrasound or massage/manual therapy. About as passive as we've gotten has been using k-tape.

I have HSD, and having a hypermobile SI joint is a concern, plus I have SI joint pain and hip pain that is consistent with a labral tear or FAI (aka hip impingement). All three can be treated with injections to address pain. But also the physical therapy approach is the same--it relies on a program of core, hip, and glute strengthening to help stabilize the muscles around the joints to prevent excessive mobility. That's what's in the home program I've been prescribed.

For SI joint pain, some people (those with hypermobility included) get relief by using an SI joint belt. It helps provide additional stability. I've not tried it yet. They're kind of expensive, so I'm waiting until I see my pelvic PT. My physiatrist said they have ones patients can try in the clinic to see if it feels like something I'd want to try regularly. The brand she recommended is Serola.
