lol, bro... Save your hair line!

Test E does cause pain in some people, whether it be the ester or, in this case, the amount of BA in your batch.
Take into consideration, the amount of shaking, and the already damaged muscle that you injected with 1ml of a substance.
For one, the muscle is already in a damaged state and you introduced a foreign entity.
Two, you're just nuts! Calm down

Honestly, at this point, nothing you can do except be calm. The combination of everything you did in this scenario is causing you pain.
Wait a couple days, and massage it in the "mean time".
There are even instances where some medical facilities administer injections without any sterilization of the skin before hand. They dictate in their own studies, that it is not that large of a factor, as I dictate that you can never be too safe.

You're fine.
