Lesser of Two Evils : Benzodiazepines or Opiates for severe pain

[Fantasian]

I have explained SWIFantasian's situation in several posts but here it is in short.

He gets severe acute abdominal pain down and left of his belly button, he is still undergoing many diagnosis for it and has had many tests but still to no avail. The pain is excruciating and needs some sort of treatment. This is where SWIM's decision becomes difficult. The pain lasts for 8-12 hours. The pain occurs EVERY WEEK!!!

SWIM can take narcotic opiate pain relievers like morphine and such but then he suffers from physical withdrawal for 3 days and psychological withdrawal for a further 3 or 4 before the whole experience startsagain. He cant live like this! For this pain relief he also mustgoto hospital to get IV morphine every week!

SWIM's other choice is thathe goes to hospital and is given IV benzodiazepines normally a large amount and a mixture of diazpeam and lorazepam which literally sedates him so much he's knocked out for 12 hours. SWIM has never had a benzo addiction but sees this as a potentially dangerous way in as well as not wanting to have to use either of these drugs for pain. Also this makes SWIM very depressed and drowzy for 4 days.

Basically SWIM is wondering if anyone else has a further alternative as SWIM can't carry on living like he is. SWIM can't fight through withdrawal and then be ok because he has to redose to cope with the pain.

SWIM has tried Cannabis with little effect, Ketamine but it just made him sick, nitrous oxide which helped a bit but wasnt strong enough.

Thanks for the input guys.

Basically im wondering which is the worst of the two from a danger point of view of withdrawal and long term use?

ANd also if you can offer a suitable alternative...
