Missyou
Don't worry. You are good with that report. When I got my medical report, the limit was 10 mm. If the swelling is morethan 10 min, then the doctor would suggest X-ray. In my case it was 12-15mm, so I got an X-ray. For my wife, it was 8 mm. We didn't get X-ray for her. Though I am not approved yet, I know cases which are approved whose reading was less than 10 mm.
