Hi, I have had both my hip busars removed. I think the pain you're feeling is from your hip. I have to have a hip replacement and my symptoms are just like yours.
Thigh pain front and back, groin pain front and back, yes? It's probably the hip itself. Good luck God bless

Hello @cindymattern, I combined your new discussion with your first discussion on your piriformis muscle issues and your cortisone shot.

I updated the title a bit to help other members join your discussion, "Post-TKR Piriformis Syndrome - Cortisone Shot?" - https://connect.mayoclinic.org/discussion/piriformis-syndrome-1.

I have many lower joint issues as well (fused ankle, end-stage arthritis in other ankle and a total knee replacement that is 18 years old in my right knee). I know that when one area of my lower body is hurting that I subconsciously compensate and by doing so I disturb other joints or muscles. For me, this causes a "jumping around" of my pain points. They seem to go from one area to the next and so on.

How is your mobility during the day now that you are 4 days removed from your cortisone shot? Are you able to move more during the day and is your pain maybe "catching up" to you at night? I notice my pain and swelling most when I finally settle in for the evening and the day catches up to me.

@christine5 is right…groin pain is often related to a hip joint issue, and the pain is referred.

But there could be many potential causes of the pain you’re describing. For example, I have front of hip pain that occurs often with low back/sacral pain. It often refers down my groin, and I have pain behind my right leg and thigh like you described—it’s more like muscle pain.

The diagnoses (yep, plural) we settled on are: hip osteoarthritis (causes by hip dysplasia)—that’s causing the front of hip and groin pain, coccydynia (tailbone) and pelvic floor tension myalgia—my pelvic floor muscles are overly tight, which is causing the pain behind mg right leg.

All the above can also cause bursitis.

Specifically, I have the most tightness in the obturator internus muscles that run from the front of the pelvis to the back, behind the leg—that’s what’s causing the pain.

Totally confusing, right? The pain didn’t get better because I had the wrong diagnosis at the beginning. Injecting one muscle with cortisone if a different root cause is prompting the pain sometimes won’t help. Or the injection can refer pain to another part of your body.

You might want to give it a few more days to see if it calms down?

I’m not sure what type of provider you’re seeing, but I got the most accurate answers from a physiatrist (physician in physical medicine and rehabilitation specialty) as opposed to an orthopedist because they look more at the big picture, and a pelvic PT—they have much more specialized training in pelvic floor, hip, and low back pain.

I am ten weeks out from TKR.
My hip ‘blew up’ form constant PT. I have had past glute/periformis inflammation.
Friday I just had a dry needling session from my PT.
The hip is quieting down! But of course my PT is also conducting manual hand release sessions when we meet too.
