Canfoot nunbness and leg weakness be caused by shingles in chest ?

Vzv: Sshingles can cause separate neurologic manifestations (neuropathy, myelitis, etc) from the rash and pain. Would be very unlikely to occcur at same time.

Possibly: Typical shingles follows an intercostal nerve across the chest, but rarely may infect the spinal cord and create a transverse myelitis. Thus, leg and foot numbness and weakness are present. A thoracic or cervical MRI may show a focal area of infection. However, other explanations include medication reaction or peripheral neuropathy of alternative causation. Your neurologist can help.
