I have a duplex kidney on the right..I've been ill for 3 months, having palpations, sickness, diarhhea, exhaustion, lower back pain for a few years but worse for last 9mths.. hardly eating, lost a stone. my doc put it down to anxiety.but I ended up feeling very ill one night went to A&E, showing every urine test positive, blood, white cells etc..now waiting to see specialist...do you think it's more likely to be my kidneys ot anxiety?
