Oh dear, so sorry to hear you're going through this, sakit masa kencing selepas cabut tiub tu memang tak selesa langsung. Someone in my mum group mentioned that after the catheter is removed, the urethra can feel quite sensitive and irritated for a day or two, which is why ramai yang rasa pedih or rasa macam air kencing tak keluar lancar. It could also be a sign of urinary tract infection (UTI), especially since hospital environment and the catheter itself can sometimes introduce bacteria, so if you notice any senak, demam, or the pain gets worse, that really needs to be looked at promptly. Every birth experience is different too, so it makes sense that your first caesar felt nothing like this one, your body responds differently each time. Please do check with your doctor or specialist soon, just to be sure it's nothing that needs treatment, because your recovery and comfort matter so much right now.
