I was in a car accident on Sept. 13. I went to the doctor on the 20th. He said I have a strained back and it will take about 4 weeks or so to get better. He advised me to take it easy and not ride any bumpy/jerky rides until the last 3 days of our trip. We are leaving for WDW this weekend. This will be our first time going to WDW. I'm a little concerned about this trip and how miserable I might be with all of the walking. Any advice from anyone I would really appreciate it.
