Dh is going through a really tough time and his second week of chemo and radiotherapy. He had a solid bowel movement 10 days ago. He then went 4 days without going. Then stated taking movicol. He is been passing liquid poo but nothing else. Does this sound like impaction or just side effect of movicol? He has been taking 8 sachets for last 3 days. Should he continue with full dose for another day?
