I am sorry you continue to have numb right thigh after having cervical fusion surgeries.
it could be coming from pinched nerve in your neck or lower down in your lower back.
you probably can't get more surgery to your neck
have you had an MRI scan of your lower back to check for pinched nerve or slipped disk in your lower back?
best thing is to see a new spine orthopedic doctor at a large university setting to have your records reviewed
are you close to a large university medical center hospital?
