Mama, side pain after CS is pretty common kasi may inflammation pa at healing ang incision, pero the timing and severity matter talaga, if it's just mild discomfort that's getting better day by day, normal lang yan, pero if it's getting worse or sobrang sakit, definitely check with your OB agad ha, baka may complications or kailangan lang ng adjustment sa meds. Gaano katagal na and saan exactly ang sakit, lower abdomen side or more on the ribs? That'll help your doctor figure out what's going on faster.
