should i continue to warm it up and massage it?
You should do as others have said.
Then get someone to show you how to hit. because you are missing it and the stuff is basically rotting inside you as bacteria eat away. The good news is it sounds like you survived the first one and seem likely to survive the second. Soon your luck will run out.
there could be several reasons. first off are you using new needles each shot? Alcohol swabs? swab cooker too? when you inject do you see a lump forming as you push the plunger? Do you move the point after you register?
Maybe you have deep veins that are hard to see.
Not sure but I seriously think you should try to be more careful.
