I had excruciating pain that started mild in the morning in my back and whole abdomen area but by midnight I was in the ER. They found nothing. I went to the ER 4 days in a row and all tests were negative for anything except CRP was high. No diagnosis. I gave up on the ER and tried to control the pain at home. They found nothing pain got better gradually in about 3 months but never went away. I went to a chiropractor and got 12 weeks of therapy and an orthopedic clinic and got a cortisone shot but nothing helped. So finally got 2 MRIs in the last week both confirming that it is discitis. So it took 8 months to diagnosis it. I hope we can fix it. Did you get antibiotics and did it help?
