I am 25 years old unmarried female. I am suffering from lower back pain just above the buttock only on left side. The pain extends towards the whole leg including foot n toes. My normal activities are affected due to this pain and i am not able to sleep on my left side as the pain worsens due to that. I did X ray but thats not showing any major problem. I also usually feel bloated. Please suggest what I should do.I really don't understand the cause behind this pain. Please help
