Low Back Pain Following Recovery from COVID-19 with Spinal Abscess Due to Streptococcus oralis

“

The patient tested positive for COVID-19 when asymptomatic, then had a mild 10-day course of the illness, followed by low back pain 1 week later, prompting him to visit his primary care provider, who diagnosed sciatica and treated him with opioid analgesics. He presented to a chiropractor the following week, noting severe low back pain with radiation into the gluteal regions and posterior thighs, difficulty with ambulation, and mild neck pain. Considering the patient’s diabetes, widespread symptoms, and weakness, the chiropractor ordered whole-spine magnetic resonance imaging, which suggested possible multifocal spinal abscess and referred him urgently to a spine surgeon. The surgeon conducted testing consistent with bacterial infection, and referred to an infectious disease specialist, who confirmed S. oralis spinal infection via lumbar paraspinal needle biopsy and culture. The patient was first treated with oral antibiotics, then intravenous antibiotics in a hospital. Over 4 weeks, his spinal pain improved, and laboratory markers of infection normalized.
