hi there
i am sorry to hear of such
injury at such a young age
i have read
and i understand you have had
mri done
i would still suggest you repeat an mri of the cervical spine
and also the mri of brain
chances are he has developed some injury which might have been missed in last mri
frankly i am worried about fractures
i would also suggest you get an ncv of both lower limbs
sometimes they show some changes when mri and ct are being normal
i would suggest he be started on
pregabalin while we wait for the reports
and please stop and chiropractor till we are sure there is nothing serious
exercise in a fracture may increase the problem
so let us know with the reports
best of luck
