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?
Hello, It would be a very good bet that you are suffering from some degree osteoarthritic degenerative change in the spinal column that is irritating or squeezing either a disc or nerve root in the area of the arthritic changes.  It is very possible that the changes are calcifications or the presence of what are called OSTEOPHYTES that are commonly found in these kinds of situations.  An MRI of the lumbar spine would be much more helpful than ultrasound or any other type of imaging study.  The arthritis foundation of America has a website that is just full of great suggestions for explanations as to what happens in these types of situations along with suggestions for exercises including stretching regimens, PHYSICAL and AROMATHERAPY.  There are also dietary recommendations that they make which the foundation describes as being helpful in patients with osteoarthritis. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
