Have you ever had sonar shockwave therapy? It helps the tissues around the joint heal faster. I also had physical therapy that was too aggressive ended up with knee and hip bursitis plus IT band syndrome. Shockwave put it right. After that was finished the doctor told me to spend several months just taking short walks every day in order to let the leg rest and finish healing. Every day feels better and my walking speed and distance are slowly improving. Once the injury healed I found stairs easier. I still have to rest when I have pain if I overdo exercise. Don't know if this relates to your situation at all. Maybe shockwave will help you. Best wishes.
