I think your consultant will be conferring with others - the multi-disciplinary team - to decide on the best course of action before making a decision on where to go from here.
It may seem like nothing's being done, but it is - behind the scenes.
You may not see a doctor on the routine daily ward-round but at some point, either the consultant or one of his team will be down to see you and discuss everything with you.
Nurses do sometimes make you feel like they don't know what you're talking about, in their defence I'd assume it's because they're focused on so many patients with differing needs that they don't have the mental agility to switch their though processes quickly. Though some nurses could do with a little training in 'bedside manners'.
But don't be cowed - if you feel you're not getting anywhere, ask to see the Ward Sister and tell her about your concerns - she / he will then make an effort to follow-up on your behalf and find out what's happening.
I've had 'rabid' diverticulitis which resulted in the removal of the descending colon. It was no picnic - but the recovery progressed well and I now don't even give it a second thought.
I wish you well, try to keep your chin up and... "box-on".
