Have you read through this thread? Because people have made posts, wanting to try H and justifying it for your same reason, and it was responded to in detail.
Short answer.. no there is no value in it. Using heroin for pain is a horrible idea and a poor justification. First of all, it's a street drug so purities always vary, which makes it pretty difficult to find a proper dose.. as one batch can be super strong, and the next can be crap. Second of all, all it's going to do, is raise your tolerance to a massive level, and you'll end up having to spend a shit load of money just to get enough to hold you over. Your large tolerance will also make it so now normal prescription opiates, don't do shit, so you'll totally screw yourself.
It's very short half life will make it so you have to redose multiple times a day too to treat your pain. You'll be adding brutal physical dependency to a street drug, that is often dangerous to purchase with no way of knowing it's quality, raise your tolerance to a huge level, spend a shit load of money, etc etc. The list of cons to this idea is endless.. the pro's are basically non existant.
It'll be one of the biggest regrets of your life.
I read through a lot of the thread, I'm sorry, it's a 15-page thread. I just thought I would explain my personal story and ask, that's what the thread is here for, right? I very much respect your opinion, but I did ask for no flaming and said I already knew what the answer would probably be, so why ask if I even read the thread? I didn't sit down and study the entire thing, but I went through as much as I could recently and have viewed it several times before ever even registering... Statements like that have always made me a little anxious about posting, honestly. I understand you've been here forever and are probably frustrated at hearing the same sort of questions over and over, but every story is different and I thought this was the place to ask if you felt you still needed to ask.
Oxymorphone was...well, I can't put prices, but it was NOT cheap and I was using constantly through the day, as in every hour. I understand the short half-life of heroin, I REALLY DO. I understand it won't ever be keeping me out of pain all day, please understand that I'm saying NOTHING does that now. My reasoning is that aren't these strong prescription medications with short half-lives much the same? Fentanyl, oxymorphone in particular. Short half-life, tons of addictive potential, easily abusable. The difference between oxymorphone in particular and heroin seem almost nonexistent, perhaps only because of my ignorance of heroin. I can admit that. I also admit that I just wrote above that I had problems with oxymorph, but it kept me out of pain. The main issue with my use became the massive amount of money I was spending and the fact that withdrawal was happening literally after 2 or 3 hrs. And that there became an unsteady supply. I wasn't willing to keep using and suffering coming off of it if it wasn't always available, so I put it down. Not that easily, but I managed.
I have no insurance and no way to legally afford the time-release medications I believe might honestly help me, even if my doctor was willing to prescribe them, which I'm fairly certain he wouldn't be since he thought 1/2 of a 5 mg hydrocodone was enough to treat a level 6-8 (depending on day/what I'm doing) pain. I can't afford pain management and I doubt my doctor would refer me, he is LITERALLY the only doctor in my town willing to see me because my pain is from a fall at work, it is really a workers comp issue. I have tried, I have honestly called every doctor in town and not a single one here will see you without insurance or a direct referral from an existing doctor. Please, you can take it as justification if you like, I'm putting serious thought into this. But I am SCARED at the thought that my pain was so bad I was willing to shoot up MScontin, I feel like that's really kind of "worse", as far as my personal guidelines for drug use go. I can't picture it going any further downhill than putting extended release medications in my veins and before we go into whoring yourself out, selling all your belongings, etc I will just say that you might be surprised (or probably wouldn't be) at the lengths simple poverty can drive a person to. Meth wasn't a cakewalk either.
My tolerance to anything goes up in days, luckily it seems to drop not quite that fast, but relatively quickly. That has been my issue with the pills, that and they are horribly expensive compared to H and never in a constant supply. I'm already plugging to avoid as much apap as possible, but I can tell I'm still absorbing a lot of it as I get the traditional feeling I used to get taking them orally from too much apap. It is not the oxy, the apap makes me throw up and I'm worried about how much I'm taking in and the state of my liver. I can't ask my doctor about it. I feel like I'm quickly running out of options on what works at all. As for physical addiction, I already need to take a small dose of methadone if I have no opiates, I am already physically addicted to opiates. I can't stay with my boyfriend when I'm out of medication because I wake up kicking the living hell out of him, whole body shaking and seizing, and the sheets soaked in sweat. I'm already there.
Please don't put me down, I'm HURT, I just want my pain to stop. Maybe it seems like a stupid-ass question to everyone here, but I was always taught there's no shame in asking, especially when every person is different.

I just feel like I want my old life back, even my old addicted life, if it means I actually do something, ANYthing besides lie in bed and feel sorry for myself all day. I already have hardly any friends, I can't go out or do much of anything and I'm always bailing on plans because I hurt too much that day. I can't give solid answers on when i'll be somewhere and if I do I show up late a lot of the time. My family already thinks I'm an addict, which I guess I am between getting dopesick and needing the medication to function. I'm at the end of my rope.
