Re: numbness on front of thigh
When I had recurrent symptoms my surgeon said the MRI showed some minor stenosis but the surgeon offered to go in and get to the stenosis. After the posterior cervical foraminotomy the surgeon was amazed at the severitu of stenosis. So sometime MRI don't really show the whole story.
And every person's anatomy is different to some degree. So something at L2 that causes you symptoms may cause me symptoms equivalent to L3.
When I had my recent surgery I told the surgeon "whatever you find, fix it, even if it's unexpected"
