Hi Mags and a gentle hug to you. I have mild bursitis, glute medius tendinitis and inflammation & arthritic change in the hip itself. But boy does that lateral hip/leg pain hurt! Cortisone injections did nothing for the tendinitis - what my surgeon did suggest was something called a PRP (platelet rich plasma) injection - which is where they take your blood and process it to concentrate the platelets (particular type of cell found in the blood), and then they inject it back to the bursa, tendon, joint or whatever. He tells me it often works when cortisone doesn't...but because it's much more time consuming and expensive they try cortisone first.
Oh...and when you mention about
the injections being not much help? I assume they also injected local anaesthetic with the steroid? How much pain relief did you have in the first few hours when the anaesthetic was active?
I haven't tried the PRP yet....I had a second shot a couple of weeks ago, this time into my hip joint, and I am starting to feel better from it.
Wishing you all the best
