i have been told after going to a doc with complaints of

shin pain
heaviness in legs
tingling legs/feet

that i have an extra vertebrae in my lumbar spine but it is NO big deal and not the cause of my pain
(i also have ehlers danlos syndrome, hip stability issues, flat feet, knock knees)

i have only received an xray as the doc didnt think my sx were significant enough to show anything on an mri

is this true? i am physical therapy and i wonder how that bone is going to affect my strengthening routine.
