### input:
I have been having severe (L) sciatic area pain that prevents me from sitting up to get up in the am. I have to roll out of the side of the bed. This has been ongoing 3-4 months. I do have DJD at multiple levels buts this is like no other pain I have had related to my lower back. I had a x-ray that shows Ovoid calcification lymph node overlying right lower abdomen as a incidental finding #1. I am very concerned have high history of family with RA, Lupus, Bone cancer, lung cancer, cervical cancer, CHF heart disease ,CAD, MI etc. I do have HTN, I do have fibromyalgia, neck surgery disectomy x s2. I have had bouts of low back going out but nothing like this. It is over sacrum (L) side I need some advise what I should do as far as calcification? or is there any concerns? Should I worry about my back as it is not low back its sacral... at witts end with pain

### output:

Hello! Welcome and thank you for asking on Chat Doctor! I would like to have some more information on your concern: - Does the pain worsen during the day or during the night?- Is the pain relieved by NSAID? If the pain is not relieved by NSAID, and it worsens during the night, a secondary cause (malignancy) should be excluded. I would recommend consulting with your attending physician for a careful physical exam and some tests: - a lumbar spine CT scan - an abdominal ultrasound- a chest X-ray study- inflammation tests (PCR, complete blood count, sedimentation rate)- cancer biomarkers (CEA, CA19.9, CA 125, CA15-3) may be needed to investigate for a possible tumor. You should discuss with your doctor on the above issues. Hope to have been helpful! Best wishes,
