Rehab

I went to an orthopedic today, Dr. Jay Kimmel. They took x-rays to rule out a fracture. Also Dr. Kimmel doesn't think it is sciatica since I had problems like that 13 years ago (swollen disk with no feeling in my lower right leg for about 6 months). So I'm starting physical therapy on Wednesday.
I just biked 15 miles with no pain and when I told Dr. Kimmel I was signed up to run Chicago he said don't rule it out yet. I had a massage/acupuncture today and Shannon said "you ran your race in Boston, just go and run Chicago and don't worry about the time." I hate to pass it up when I'm registered and my flight is booked. My physical therapist is a marathoner so I'm praying I can rehab in time.
