I am 50 yrs old, female, good shape, within last 6 years have done triathlons, marathons. Normally run 4-6 miles a day, 4-5 days a week in the morning. Take plenty of supplements, probably don t get enough water. Take NO prescriptions, no ailments. Have suddenly developed lower back pain, right side, works its way around to my hip and groin, sometimes shoots down my leg. Can t run now. Going to chiro, says maybe nerve or calcium deposit. Doing ultrasound on the spot. Not helping. Thoughts?
