Hi, I am a healthy 44 year old female, with two teenage sons, who developed a sharp left lower abdomen pain yesterday afternoon that comes and goes approx. every few hours. It woke me in the night once. I had microdisectomy for herniated discs 6 wks ago which i have recovered fine and just began back at work yesterday. I currently only take vitamin D 2,ooo U and Vit B-12 250. Anyways, I'm wondering if this may be from gas, food poisoning, something to due w/ period coming in a week, or should I be concerned at all, because I do not have any urinary symptoms, back pain, fever, nausea, or even tenderness in LLQ when I press on it. Please help. Oh, I'm 5'3.75", wt 117, and only had nephrotic syndrome around age 7 - 8, which after predisone treatment and 2 yrs of being followed up, I had no kidney complications.
