Oh dear, so sorry to hear you are going through this, tiga bulan dah lepas tapi masih sakit, mesti rasa very uncomfortable and worrying. Sembelit memang boleh put extra pressure on that area, so do try to drink plenty of water and eat more fibre (buah-buahan, sayur) to help soften things, and please avoid straining too hard when you go to the toilet as that can really aggravate the stitches. My friend who had a similar experience said her doctor reminded her to always rinse the area gently with clean water after each time in the bathroom, and pat dry carefully, just to keep it clean and reduce any irritation. Since the pain has come back at this stage, it would really be best to see your O&G or a doctor as soon as you can, as sometimes it may indicate something that needs proper attention beyond home care.
