Soreness in deltoid

[superdave10]

I recently started a cycle using test prop and dbol. I inject test prop on tuesday into my left delt, and it started to get sore that night, and is still sore, and it is now thursday. The pain isnt at the injection site, its more at the bottom of the delt where it ends.

What do you think it could be??
