Ooh that's common after CD, iba-iba lang severity sa bawat mama! A few of us had that din, kasi ng swelling or sometimes irritation from the bandage area, plus hormones pa rin doing their thing. I'd definitely check with your OB about those rashes just to be safe, especially kung umiikot sila sa incision or kung tumataas ang intensity, kasi pwedeng skin irritation lang or something that needs a quick look-over. In the meantime try to keep the area dry and clean, and wear loose, breathable clothing para ma-minimize ang friction. Feeling mo ba it's spreading or localized lang sa legs mo?
