Had to inject iv valium, but couldn't find vein on arms. only on hands. kept missing. finally injected & it made knob which disappeared in minutes.

Ivdu valium: I'm sorry to hear that you're struggling so much with what sounds like benzodiazepine addiction. You may have had what is commonly called a "blown" vein. Most importantly, it sounds like you need to enter a detoxification and drug treatment center. IV drug use carries significant risk including hepatitis and HIV. Please think about detox today. Treatment for co morbid anxiety will help.
