i had an mri of my lumbar spine and the impression was : Right paracentral disc extrusion with downward migration of disc fragments, l4-l5 . did two months already of PT and improved a lot except sligth weakness on my right toe and numbness on the right side of my lower leg. My question is, when will this slihgt weakness in my toe and numbness be gone? will continous therapy still continue and for how long? overall, i can say the strength of my leg leg is still ok during doctors test. thanks for your help..
