I have left lower abdominal pain but more on the left buttock like when you have sciatica. I have no pain on the right side at all. Only on lower back. I have had my blood test which was 19 and then rose up to 46 in 48 hours. I had a scan as well but they could not see anything as I am only about 4 weeks. Anyone have had this problem before? I am really anxious.
