What is the twitching when injecting?

[CockedDiesel36]

hey stupid question, i know. But i was wondering what it that twitching that happens sometimes when i pop the needle in. obviously its a muscle ,, but what is it doing?
seems sometimes when i put it in and it twitches, halfway through the shot, the syringe will blow apart... is this pretty weird or normal?? bleeds alot too... thanks for the help....

Its your leg talking to you 'wtf are you sticking in me, you a$$hole?!'

Happends to me too, nerves?

Yup, nerves, happenes to me all the time

nerves, and the severe bleeding is you probably passed through a vein during the injection

sometimes when my leg isn't fully relaxed my muscles twitch.

Have you had a needle literally be forced back out of the muscle? I think it's because your forcing a foreign object into your muscle, so your bodies immediate reaction is to contract the muscle and push whatever it is out. The small twitches are just nerves I believe.
