My 38 year old son who did a lot of road running in his teens and worked as a cycle courier in London for around 10 years. Restarted running over the past few months but had to discontinue because of hip pain (only the right hip). Had x rays which showed formation of osteophytes (?calcium deposits) on BOTH hips. Now awaiting MRI scan - don't know whether this has been around for some years and therefore is slowly progressive i.e. ok for another 20 years or so.
My advice is to check with your GP - good luck!

Your pain sounds similar to my experience...so I'm wondering if you might have the same thing. I had hip pain that started when I was 11 or 12 and was written off to wear and tear since I played a lot of sports. It wasn't until I was 16 and finally got an x-ray that they found it to be hip dysplasia in both my hips.
Dysplasia is usually caught right when you're born but I guess mine didn't present until later. Anyway...have you ever had an x-ray? Because that is all that is needed to diagnose hip dysplasia. I am 20 now and have had a ganz osteotomy or PAO done on both of my hips. It is an intense surgery but in my opinion well worth it. I have had excellent results which eliminated my pain and I'm back to being just as active as I ever was. So my suggestion is go get a pelvic x-ray and I hope everything works out!
