I have had hip pain (right hip, shooting into my thigh, knee and into my shin and foot) for over 10 years. I’ve had x-ray investigations (mild arthritis, but nothing anyone wanted to follow up on), loads of tests for RA/ autoimmune disease (zero- appear to be super healthy), physios private and NHS, ultrasound scans to check for bursitis (nope), podiatrists NHS and private (bit of a bunion, orthopaedic referral but nothing anyone serious enough to warrant surgery as yet)to check on gaits.
I haven’t had an MRI and to those who have, I would like to ask what the MRI can identify that none of these other investigations can? I have claustrophobia and couldn’t cope with being in standard gantry without sedation, so I want to know that the MRI isn’t likely to be inconclusive before I pursue it!
Also and more optimistically to your point, OP: I have found that upping my strength training by adding weights to my exercise routines and doing squats, split squats, Cossack squats, sumo squats, lots of calf raises and foot and ankle strengthening exercises has really helped with my pain and ability to walk (I used to limp and pain would keep me awake). Ballet barre and floor barre to strengthen glutes, turnout muscles and help balance.
It has taken a lot of exercise- probably 3 times as much as the physios I used to see suggested, and over four times as long! But strengthening the muscles around the joints (as opposed to just stretching the ligaments with yoga, which I did for years) has made the difference.
I still do get pain, still am obviously weaker on one side, and still use ibuprofen very regularly, but it has improved. Maybe worth asking your physio about adding more weights/resistance to your exercises?
