What the hell is this?

[spound]

First of all, hi! I've been on this board for some time now trying to educate myself but never posted anyting.

I'm on my first cycle and taking susta @ 500mg/week (250 on sundays and another 250 on thursdays). I'll be taking my 11th injection today and this far I've had good gains, it's just that when I woke up last friday I noticed something that never happend before... take a look at the picture below. The small area is where I did the injection, the larger area is a bit swolen and hurts like f-cking hell. The pain has decreased as the days passed but I'm still a bit limp. : / Ever seen anything like this?

Please excuse any misspelling or incorrect grammar.

Edit: You should be able to see a big red blotched area. If not I'll try to get a better picture. Thanks.

WHy the **** did you inject on the top of the quad?!?!?! You're supposed to inject in the side of the quad
