If you got an infection, you'll get edema...
I got worried when i started out my cycle too but don't worry,
If your injection spot is swollen it should be due to...
-High benzyl alcohol content
-You injected cold oil
-You injected into fat
If swelling or soreness doesn't dissipate in a week's time...
you should be going to the doctor,
just tell him honestly that you're using steroids because
it'll be pretty obvious to him
