Seen this happen when disc slips and presses nerve. Pain shoots like electric line from back to leg, sometimes neck down to arm. Numb toes, weak grip, even trouble standing long. Many think it’s just muscle strain but scan shows disc bulge. Some manage with rest, careful stretching, heat or therapy, others end up on strong pain meds. If nerve keeps pressed too long, doctor suggests injection or even surgery. Recovery slow, needs patience, avoid lifting heavy or twisting wrong again.
