hii i am a track runner i have been running since sophomore  year i am currently a junior and i have been experiencing constant lower back pain where my kidneys are as well as alot of pain in my knee. i was wondering if running is causing this or is it something else and is it serious
Dear patient Running as such does not lead to back pain. But I back pain may be related to running due to sprain. Chronic back pain may also be related to spondylosis. I would advise X-ray of lumbosacral spine anteroposterior and lateral views to rule out bony abnormalities.  Visit radiology center nearby you and get it done.  Start tab diclofenac plus thiocolchicoside combination twice a day for pain relief.  Visit expert orthopedic surgeon with report.  All the best.
