IM use
I can tell you that Im use is highly risky. I have had numerous absceses due to this and many surgeries for those as well. You must use alcohol and clean works. I lost viens many years ago and this has caused major problems. I have now also ruined my shoulders.
Overall, it is effective but highly risky if you get lazy and are not careful!
Basically, I need to say that if your problem is no more veins, you need to consider recovery!
I can't tell you how many abscesses I have had and if it gets in your blood, you can die. I have been so lucky and besides that, abscesses hurt like hell and if you don't catch them quicxk, you will be headed to the OR for surgery. I had one once that was the size of a football on my shoulder and I kept ignoring it waiting for it to find its own break. You need a lot of drugs to tolerate that kind of pain for days on end (fever also). When it broke, it still ended up all nuecrotic(??) and had to be debreeded which also required hospitalization. Additonally, thse days you could end up with that type of infection (i cant remeber the name) that does not respond to regular antibiotics. Also, after surgery, you will have a gaping whole that you have to pack for weeks while it heals from inside out. I am doing recovery again myself and that is what I recomend.
