Different brands are made in different ways, using their own unique blend of solvents and oil. Some people don't respond as well as others to a specific solvent or oil. Also, the higher the Mg/Ml, the more likely it will be painful. So over dosed gear or high MG gear is more likely to be a problem.
So, yes, I can see how this can happen. I've had it happen. A shot can cause inflamation and this swelling can cause irritation in joints. In this case, it sounds like it might be the SI. I would take a NSAID like advil at 800mg and use some damp heat to loosen the area up and move fresh blood in, to help carry away waste.
If this gear tends to be painful, but it's good, you can always cut it with less painful gear, like a high quality EQ or Deca, or you can mix each shot 50/50 with sterile oil. This will help too. If you suspect that it's just poorly made gear, I would toss it and get some Geneza Test cyp or Test E. These are both top quality, smooth tests that are slightly over dosed but not very painful. If anything, I would say it is less painful than other brands I have used.
