What do you mean exactly by still testing positive? Im assuming you're being tested specifically for Methadone or??? I used to shoot up my take home doses of the liquid 1ml = 10mg so I'd use an entire 1cc horse rig to get the whole dose. One time I registered but midway through injecting it must have breached the vein walls from maybe pushing to hard or just collapsing. It hurt like hell. I didn't think anything of it because I'd missed a handful of times before but it was of other things like H. I sort of brushed it off, forgot about it & went about my usual day. A small lump had formed, but it wasn't anything different then other times I had missed, but this was a first missing this particular drug. A few days to a week later I woke up extremely sick, very high fever & the lump had swollen to a massive size. I missed in the crook of your arm, where most people IV, and the swelling was so bad I couldn't bend my arm at all. Extremely painful & very Hot to the touch it was literally on fire. It was all bad dude. I was freaking the hell out & had my buddy rush me to the Hospital....
While waiting for the doctor to come see me in one of the patient rooms I started puking, and my fever blew up. The nurse checked my temp & it was 103. The swelling seemed to be increasing by the minute, and right before the Doctor came in it started to itch intensely just before it erupted! It literally exploded gushing out some of the most foul smelling/pussy substance I have ever seen. It was a nasty green color with thick chucks just pummeling out of the wound. The nurse had to cover her nose to keep from puking while she tried to clean it. Just as she was wiping up the gunk the Dr. came in quickly assessing the damage to being related to IV drug use, which I replied that indeed it was, and that I was addicted to IVing speed/stimulants in hopes that he wouldn't try & refuse me pain medication if he knew it was from opiate/opioid abuse. I don't think it would have went different either way, but who knows? He basically went real smug, & said something along the lines of "This is what happens if you play around with your life doing risky things such as injecting toxic street drugs into your arm...."
Then very quickly without warning or saying anything at all he cleaned the wound then made an incision to open it up & proceeded placed both hands around the swelling with what felt like all or most of his weight down on my arm to squeeze out all the puss. This was horribly horribly painful, and came without the slightest bit of a hint it was about to occur. I believe him seeing I was an IV user had him relieved of any sort of empathy towards my suffering, and just how much it would hurt me which in regards to how society views drug addiction was not surprising in the least, & was something I already assumed would be the case so I just bit my upper lip, and tried to focus on a point somewhere in the room until he was finished. After he got much of the puss out of what was now a gaping cavity in my arm he took a bottle of anti-bacterial string/gauze to fill the wound with. He was not gentle about any of it whatsoever, and stuffed almost the entire length of string into the wound which I later found out from a different more passionate doctor in my wound-care followup was overkill, and not nearly that much of it needed to be used.
After it was all said & done he hardly spoke much at all. He ordered me a prescription of Ultram for pain which is nonnarcotic which due to the whole situation was fine with me. No little thing like Vicodin would have helped ease any of it anyhow for me at the time. I had just asked for the time being while in their care if I could be given something to help somewhat. He looked at me reluctantly & had the nurse go and fetch a 10mg Hydrocodone tablet. Although it didn't do much in an analgesic matter it helped elevate my symptoms overall. They gave me documentation on how to handle the wound with instructions to go to a wound-care followup clinic in 24 hours. A wound of this nature must heal from the inside out naturally, so it's not something you can get stitched up easy-peasy. I had to live with a gaping hole in my arm for several weeks until it was healed. I had to shower with my arm hanging out to not get wet, and a bandage at all times. After I left the Hospital as soon as I got home I of course did what just about any addict in the depths of their use would do....I sat down & cooked me up a nice shot of some black tar & slammed it in my jugular since my main spot was no longer of use. This is the illogical & ridiculous mind of an addict of not only the opiates, but the method in which its administered ie- IV because any reasonable minded person would have simply ingested it differently or maybe had the sense not to touch it at all whatsoever. All of it in such control over me that even though I could have nearly died or lost my arm from sepsis I still continued to inject anyhow.
Point being if you're an IV user & if you miss IV'ing, especially after a substance like Methadone which is one of the worst things you can inject due to all the fillers, sugars & such condensed in quite a thick liquid you will have a broad chance of infection. If you can avoid it don't shoot Methadone whatsoever. I continued shooting but my justification was that as long as it wasn't Methadone anymore I'd be fine which is all nonsense because it can happen administering any drugs. Be careful, be clean, & if you feel you're missing get out immediately! Apply pressure on the spot & clean it thoroughly. Keep an eye on it afterward while it heals. If you start to feel anything wrong at all/develop a fever or the site begins to swell go to a doctor ASAP. Let this be a warning, and I hope its of some use I shared this cautionary tale to help prevent harm for someone else. Be safe folks! Ive had friends who had it much worse than I with infections in multiple injection sites come about all at once after routine IV of methadone liquid. Their wounds were quite grotesque eating away at flesh all throughout their arms. One of whom in particular was lucky enough to keep his arm, and not end up dead from how bad the infection spread. He has a scar from the crook in his elbow, all the way down to his hand where he had trouble with several injections spread out that became one disastrous mess.
Cheers
