Hi I am 39 years old female, having lower back pain since last 4 days, I took vitamin D3 injection and felt 50 % better.I still had pain (more in right side). The pain used to also ripple effect in my calves. I took an X-ray which shows decrease in L5 space. Can you tell me what are the treatment options available. Do I need to take compulsory bed rest. What exercises are there which will help improve my condition.
