Known FAI and Labral tear but recent major flare up

Im a 24 year old woman and I was diagnosed with FAI (CAM and Pincer) and a labral tear over 10 years ago, I have done PT and had a steroid injection (probably like 8 years since the injection), I have overall done pretty well and have not had a ton of pain, its been well managed with PT. I did meet with a surgeon back when I was diagnosed but due to me having a bleeding disorder and lung disease surgery was too risky. I am a distance runner, I have run 3 marathons, a couple ultras and a bunch of shorter distance races and have been training for my 4th marathon this winter and spring, things were going really well, I typically run 50+ miles per week with zero pain or issues (and this is not an increase in mileage), I strength train and I cross train, I havent had any injuries. Well, suddenly 3 weeks ago out of nowhere I starting having pretty bad anterior hip and groin pain, to the point where it is significantly impacting my walking and sleeping and I cannot run. My first thought was a stress fracture since I have osteopenia, I went to my doctor, had scans done and it did not show a stress fracture. I went to my PT who felt that based on her evaluation this seemed like FAI, however, we cannot figure out why it went 0 to 100 with seemingly nothing provoking it, I have never had pain like this even when I was first diagnosed. I have an appointment with my sports ortho next week to see what next steps are but im so frustrated and stressed about not being able to train and potentially having to pull out of the races im scheduled for. Any ideas for management in the mean time? The other tricky thing is that I cannot take any NSAIDs due to my bleeding disorder. Ive been using ice and foam rolling but so far nothing is helping. The other complicating factor is that I have an autoimmune disease that causes inflammatory arthritis, it is mainly in my hands and wrists but now my PT is wondering if that is potentially a contributing factor.
