Chronic foot injury (interosseous strain and stress fractures)

Hi all,

Over two years ago after I had run a marathon, I was diagnosed with an interosseous strain in my foot. I didn't think much of it - wore the boot, rested, etc but I never got better. I've been in a boot on and off, had long periods of PT where I focused on strengthening, received custom orthotics, etc. and my injury keeps getting worse. I now have stress fractures in both of my feet as well and it's becoming almost impossible to walk even around the house. I've tried extended rest in boots/on crutches and also really dedicated myself to PT and everything in between, and no luck. I am 30, female, and otherwise very healthy and in shape. Arthritis has been ruled out, steroid shots have not helped, Prolotherapy has not helped, dry needling has not helped, high level NSAIDs have not helped... PRP is so expensive and I'm a doctoral student.

Has anyone else dealt with a similar chronic musculoskeletal injury and have you ever figured out how to improve? My next steps are to ask about prolozone, maybe try extracorporeal shock wave treatment, MLS laser therapy, bite the bullet and do PRP, enter a rehab program at Spaulding....it just all feels like a shot in the dark, and in the meantime, even daily living is becoming really stressful and I just want my life back.
