Normal lang yan sa 3 weeks post-CS, mama, the incision is still healing and may kasama pang gas or constipation na common after surgery, kaya ang puyat at stress ay nakakapagsama pa lalo. Try warm compress on the area, drink lots of water, eat fiber-rich foods, at iwasan muna ang heavy lifting or straining, pero if the pain is getting worse, feels hot, may pus or unusual discharge sa incision, or hindi na kayo makayanan, better check with your OB na agad para sure walang infection or complications, better safe than sorry!
