hi,Here's my piece of advice as a midwife and natural therapist (qualified massage therapist, reflexologist, and iridologist). Leave the cortisone until it is a last resort.... give massage, acupressure, accupuncture, reflexolgy, kinesiology etc a go first. Or go to a good sports injury specialist. Get a lot of opinions. (doctors are often busy and like things that fix problems quickly... other therapists can take more time)
