I started suffering from a lower back ache a few weeks ago, along with fatigue. Due to holidays I couldn't get in to my OBGYN or family doctor so I went to a quick care clinic where I had a urinalysis. I had a few white cells, some blood and protein in my urine. I was prescribed 5 days of Bactrum. Symptoms subsided for about a week. This morning I noticed the lower back ache had returned. I am pre-menstrual and have always had bloating, fatigue, soreness of the breasts before my period, but never this.

Have any of you experienced this before? Any ideas?
