i'm sorry you're going through this. pain issues can negatively impact a person's quality of life and in your case you've had to reduce your running because of it. if it's been a year since you last saw the doctor about this it's time to go back. for one thing you now have additional symptoms in the knee and heel. for another thing even if the pain were confined to your hip the fact it has not gotten better over the course of a year means you deserve to have it re-checked. many conditions can cause the pains you've described. anything from sciatica to worn cartilage in the joints to arthritis could be the culprit. if you don't feel your doctor did an adequate job in diagnosing your condition feel free to get another opinion. i wish you all the best!
