Suffer from left foot drop and numbness. Taking prednisone. MRI showing bulging disc and mild stenosis. Due to viral infection? History of shingles

I am 40 years old and female. I have had left foot drop and numbness on top of my foot and and up to part of my leg for 8 days, sudden onset. I was seen by orthopedic doctor on monday and placed on prednisone , 12 day dose. I had xrays and MRI, MRI showed bulging disc at L4 L5, L5 S1 with moderate stenosis, no herniated disc. My doctor suggested it could be a virus that has caused this. Is that possible? I am some better with a little movement and less numbness but still have to high step to walk. I have a history of shingles 3 times since 2009.

Thank you for posting your query.

Foot drop can be due to disc prolapse at L4-5 level also, if the compression of the nerve there is severe. However, in this case, we expect a sharp, shooting pain from low back to the foot region.

Foot drop can also occur due to involvement of peroneal nerves (located in the leg). This can occur due to a viral infection. So, I would agree with your doctor.

Current treatment is alsong correct lines, with physiotherapy being the most effective. A foot drop splint should also be worn.

Please get back if you require any additional information.
