I've been have pain in my lower left abdomen for 5 months now :( It comes and goes, last about 2-3 days and then disappears for a week or two before coming back. I've been at A&E twice as the pain was so bad. Urine tests show blood in my urine (small amount) and my white blood count is slightly raised, but not enough to worry the doctors 
I got a CT scan last week and am waiting for results and managing to diagnose myself with all sorts in the meantime, thanks to Dr Google.
Every doc seems unable to say if its a gynae issue or bowel related, as they think the pain is too high to be gynae but the pain does seem to flare up with my cycle.
Sorry this is so long, I have managed to worry myself sick over this. Has anyone had anything similar?
