Thanks for reaching out and thanks to my colleagues Dr Henry and Dr Sean for their excellent answers. I’ll try to add something from a Sports Medicine/MSK/Rehab perspective that adds to theirs.
As Dr Henry suggests, you could see a physiotherapist in the first instance for stretching of the ITB, strengthening the gluts and working on pelvic stability. They are excellent at assessing you from a functional perspective.
Another option is to visit your local Sports Medicine/MSK clinic. Here, with a multi-disciplinary approach, you might be assessed by a physician in the first case, with an MSK ultrasound scan which is good for many outer hip issues, followed by treatments from a physiotherapist or podiatrist. Sometimes acupuncture can also help with niggling pain symptoms.
As your symptoms came on with running, a gait analysis maybe a key step and might identify “why” your symptoms developed. Some patients require guided injections or shockwave therapy for tendon or bursal pain that is not settling, and in other situations, further assessment might include an MRI/arthrogram and referral for a surgical opinion.
Things to consider when you consult someone are:
1. Changes to your running (distance, frequency, route etc)
2. Changes to footwear
3. Whether you have back pain symptoms
4. What treatments you have already tried
Hope this adds further to the earlier posts. Bw
