Thank you for posting your query.
At L5-S1, the chance of hitting the spinal cord
is nil, as the spinal cord ends at the lower border of L1.
So, the doctor most likely hit one of the nerves that originate from the lower spinal cord. All the symptoms can be explained on that basis.
For relief, you could take medications such as gabapentin
Wishing you good health,
