I Have Chronic Heel Pain. I've Had This For 6

I have chronic heel pain. I've had this for 6 months. I've been to a podiatrist, orthopedic surgen, physical therapist and no one knows whats wrong. I've had x-rays, an MRI, and bone density tests, with the results that I have tendonitis, no spurs and not plantar fasciitis. What should I do now.. And I am still in pain. OK I just went through 50 people who have the same foot problem, and no one has had anyone help them!!! Do we have a real medical horror story here or what. And most have had the pain and the drugs for 6 years. This is incredible!!!!! And what will this question cost?
