<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am 25 yrs old female married, I feel pain at the lower back near the end of spine after standing for about 20mins continuously. When I sit lean forward the pain raises very high stops in few minutes. Kindly suggest me what could be the problem  <response>: Hi, thank you for posting. I have gone through your query and I understand your concerns. I think that you suffer from Sacroiliacs. It is the arthritis of lower vertebral column. To confirm the diagnosis you need fibrinogen test, x-ray, complete blood count and urine test. To treat it you can take non-steroidal anti-inflammatory medications such as Meloxicam. Consult your neurologist. All the best.
