Hi, im 20 years old. I have been experiencing lower back pain since the age of 10~ after an incident. For the past year I ve had pain on and off in the pelvis area. My chiropractor says its pelvis displacement, she can usually replace it and the pain goes away. My doctor never recommended testing/x-rays, never actually looked at me, she just said it was because of a lack of exercise and it should go away with Tylenol or Advil (but it doesn t seem to work). If I work out sometimes it will get displaced and it is very painful. It usually last 3 days to a week.
