I had the exact same pain years following my hip replacement in 2021, I had several steroid injections and another MRI to make sure the components where all in the proper place and they were, it turns out I have iliopsoas bursitis and it’s very tight , I had the release procedure done in December 2024 at Mayo by Dr Mario Hevisi , I think I spelled the last name wrong but so far it feels a little better I am doing PT three times per week to try and strengthen my hip/ legs and stretch the muscles I’m hoping in a few more months I will get more positive results .
