I injected meth into my left bicep area 24 hours ago and I missed cuz I had someone else hit me for the first time (usually I do it myself and never miss) but she kept going once it started burning.it wasn't until now did it start hurting really bad when I move my arm and kind of stretch the muscle, its a little swollen, is not red, but it hurts really bad when I straighten my arm, its also a little bit warmer and it kinda feels like it's spreading down to my elbow and up into my armpit. its not hard and hurts when I touch it... what is it??
