The doctor said go to a and e which I think 111 should have advised.
This is the problem with 111. At least NHS [re]direct had calls answered by nurses. Which meant that although they were a bit ambulance-happy when it came to breathing issues, meant that they'd hopefully have sufficient medical clue to know that urinary retention is a proceed directly to A&E job, or that you don't treat known faecal impaction with para-fucking-cetamol.
Unfortunately, proper out-of-hours services have basically evaporated, so you're stuck with 111, who will take ages to call you back, read from a script, then pass your details on to a third party service, who will finally manage to get someone medically qualified to contact you about half an hour after your GP opens the next morning.
Anyway, hope
TEH GOOD DRUGZ help, and you aren't stuck with the extra plumbing for too long...
