Yes I do, the same location as you have on both sides and it can be ridiculously painful. I'm under Rheumatology for other conditions so it was them who diagnosed it and have been treating it, so I'm lucky I'm already under specialists who deal with this kind of inflammatory issue.
I've had it for many many years now. I have had some physio but the only thing that has really helped mine are steroid injections. My first one was done by my consultant and ultrasound guided. Further ones have been done by the specialist nurses, more a prod to find the most excruciating bit and inject there. I've always had a lot of relief from them and they work very quickly.
For me, it always comes back, but I have Rheumatoid Arthritis so other inflammatory things seem a bit par for the course and can often become recurrent/chronic. So it wouldn't necessarily be the same for you.
