Hi. Hope someone can help with a suggestion for severe constipation. Having had lower resection surgery and reversal for bowel cancer almost 4 years ago now. I am really struggling with severe pain and constipation, which has slowly got worse over the last 6 months to the point that it is now often 7 or 8 days before passing any stool. Even then the size of a `Maltesers`. Spoken to my GP several times and been informed that constipation can be treated with over-the-counter medicines and no longer prescribed by the NHS. Also, unable to get to see a doctor face to face only by telephone chat after trying for the last 5 weeks.  I have tried both natural treatments, Fibre gel, Dulcoease and now Dulcolax. Despite avoiding foods that are difficult to digest since my three operations, as well as eating a lot of green vegetables, fish, wholemeal bread, and fruit, none of which are having any affect. Thanks.
