After years of on and off pain in my left hip flexor a physio has just diagnosed me with snapping hip syndrome. It's starting to get more and more painful and flares up after about 10 minutes walking and just gets worse and worse until I can rest and ice it. It definitely feels like the tendon is rubbing over the bone and getting inflamed with movement. I have exercises to do, anyone else had this and managed to get pain free? Missing walking long distances and running!
