Yesterday I injected 0.75cc tren into my right quad - on the top outter part.
Was a little sore as usual but nothing major. A couple of hours later I started to get a bad pain just above my kneecap (directly in line with where I shot). Today it's swollen up like an egg and hurts incredibly - not red at all though.
I could understand if it was the spot where I actually injected, but it's a good 10 inches away.
What's going on?
