TLDR: Recommend some glute activation and strengthening exercises.
Long story long.
Last year I started suffering from a pain in my right hip. As we had no racing I decided to take time off the bike and see if it was anything to do with it. No joy. So I tried to get some medical help, which turned into a scary adventure. Turns out I have a family history of ankylosing spondylitis which crippled my fathers hips in his early forties. Due to the pandemic progress is slow but I have been x-rayed, mri’d, poked, prodded and drained of blood. My last visit to a spinal specialist was the most positive as he is a cyclist himself and saw me as a cyclist not just a patient. He is not so sure about any long term anti-inflammatory conditions based on all the results but did comment that I do have a week right glute which if I could get working more efficiently will ease the pain while riding. His exact words were to smash the glute exercises!
