Friday night I awoke feeling like my leg is being electrocuted. I am having 1-3 second shocks every 30-60 seconds like clockwork. I am 15 months post fusion L2 to S1. I was doing great. CT scan shows evidence of loosening screws at L3, L4. I am having pain across lumbar area, up and over left hip to inside of L thigh to L great toe. I feel like a tight band around calf muscle. They want me to see the neurosurgeon tomorrow. Anyone else with experience of loose pedical screws causing new symptoms and what was your treatment? I am confused and terrified!
