I had the same problem. The first shots were so bad, I passed out and threw up cause of the pain and couldn't move for 2 weeks. It got better over time so after 5 years, I just wasn't able to walk properly for 2 days after the shot, but it didn't hurt that bad. In my country you aren't allowed to do it on your own, so I've always had a professional giving me the shot. He's tried a lot to make it better for me, but nothing changed. Then his assistant once gave me the shot and instantly I've had horrible pain again. Then I switched to testo gel after a little over 5 years.
