Does Hepatic Cyst In The Liver Cause Lower Left Abdominal Pain?

I have had lower left abdominal pain since the friday before christmas. I went to my Urologist for a KUB thinking it was a kidney stone, He said that there was none present on the film, He sent me for a ct scan w/o contrast nothing present there. He sent me home. Pain got worse. On the 12/29 I went to the ER with more pain at his request for a CT with contrast. Still nothing. I was sent home with Flagyl and Ciprio for 7 days. No diverticulitus was present on either scan. My questions are: the pain is still present, I have no female organs full hysterectomy was done several years prior. I also had a bladder lift which my OBGYN had just said on the 27th looked great. There was a 12mm hepatic cyst in the liver. My concern is the Pain in the left side the and constant nagging ache with some occasional stabbing sharpness. I have told the doctor i do not want pain medicine. I still have the stuff he gave me. I really would like the problem fixed. I am a little concered about the liver problem. I don t see my GP until March, Or MY GI until the end of Feb can this wait? What could it be? Please advise.
