I have adult polycyclic kidney disease, ache in lower abdomen, is it normal?

Age 43 female I have adult polycyclic kidney disease diagnosed when I was 27. Been taking antihypertensives since. Had dull ache in lower abdomen past 3-4 weeks, also has progressed to stitch like pain in both sides, although this seems to move around. Tummy feels inflamed and I feel bloated, reduced appetite. Feel tired. Urine tested no blood present. Saw go last week who gave me co codomol, when the pain became acute all of a sudden, have stopped taking now…. I suppose I just want to know if this is what I can expect from having apkd or if it’s a stomach thing…..
