Sorry to hear about your pain. A few months after I started riding, I took a tumble back first on some rocks, and I've had pain every time I've ridden or jogged for the last 3 1/2 years. I did a few months of physical therapy, but they recommended a program of a year or more, which I felt was soaking the insurance company so I turned it down.
Here are things I can think of, although it may be none of them will help:
Try a different saddle. The Aussie-style saddle I normally use is more inverted V shape than inverted U like the western saddle we own. I find it allows me to hang my legs down straighter without pull. Maybe a different saddle would fit your hips better.
Try a different event.
Don't stretch. I used to stretch before jogging, but I found I hurt less when I skip the stretching and just jog gently for the first 1/2 mile. When stretching, it is very easy to stretch the wrong spot, or to loosen something that is better off tight. I'd try skipping the stretching, and just ride gently at the start - maybe 5 min walking, 5 min of walking with lots of turns, then 5 min of light jogging.
Maybe try a different horse. Some of the horses I rode when taking lessons had backs like table tops. The Arabians I own are fairly narrow, and my legs hang down straighter on them than on most lesson horses.
Like I said, I've been riding with pain for years, but in my case it is getting better. You might also try some cross training, like bicycle riding or LIGHT jogging.
