Sorry to pop in with a Dad update only - blood in stools, call with cancer doc on 15th (can't come soon enough), 6 week follow=up with hip doc, xray showed a crack in hip. They asked if he had fallen again (!!!!) which he hasn't. Dr Matz said it will heal on it's own. Completely bizarre to me and to Dad. Lots of foot pain still - Matz suggested referral to see Ahmad again re blockage which Ahmad ruled out with ultra-sound. Poor Dad suffers on with hip and foot pain.
