<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have ulcerative colitis and was involved in a rear-end hit and run car accident three weeks ago. I am having constant lower abdominal pain. How do I tell if the pain is from the colitis ive been in remission 3 yrs, the actual force of the accident, stress or from the chiropracter pushing on my body twice a week trying to relieve the whip-lash?  <response>: Hi. Thanks for your query. The treatment is more important to start with than the real diagnosis... Why !! Is very important, but after you get a relief too. It is better to go for a CT scan of the abdomen to see if the pain is due to some internal trauma or something else. Also go for colonoscopy to whether the ulcerative colitis has re-started troubling you. The treatment will depend upon the diagnosis.
