I Have Pain Around Liver (first Time) - What Can

I have pain around liver (first time) - what can it be? other symptoms I typically have - low iron level. I tend to have high protein/low fat/carbs/gluten, white meat/fish diet (only that 2-3days a week). I often have back pain - more recently. I have had urinary/kidney infection. I easily have bloating/pain around intestines/colon but it has disappeared by cutting gluten. I have more pain from ovulating/menstruating that I used to.
