Ooooooh. @closer0043. I reread your mri. The Radiologist uses the wording "spinal canal stenosis", and "cord signal abnormality" Where I use thecal canal impingement. You have the loss of the natural curve of tour cervical vertebrae, which can cause the clubbing from riding your bike. The most concerning area I read in the thoracic area is T5-T6/ T6-T7. That junction is notorious for wearing out, partially because that junction is where the shape of vertebrae change, in prep for the strength of the lumbar vertebrae, and partially because of Americans poor posture. It wears out naturally due to those 2 things, and playing sports doesn't help us at that particular junction. Take extra good care of that area. Your upper body strength is/will protect it.Thinning is what effacement means, and it is saying the membrane which houses the thecal sac is thinning, however there is no intrusion into the thecal sac itself....yet. You want to keep that as such. When I had thecal sac impingement, I would lose all feeling in my legs, randomly, and hit the ground. Stenosis is not good, but, until it causes protrusions into the thecal sac, which it has not, surgery is not necessary, unless there is so much pain, or lack of function, surgery is the only fix. That's why I said your mri looks pretty good. I hope this made some sense lol. Still .... so happy for your progress! -mary
