I took my first shot of tren yesterday in the left pec and it felt like I was shooting acid into me during the injection, after it swole up all day and was extremely sore. It hurt to put my arm over my head. Second injection today felt the same way like acid going in. Diddn't swell as bad but was very sensitive to touch. also after the injection I got light headed and dizzy. I had to drop the pin and run over to the bed and sit down....I was breathing properly, as I always make sure I do. Are these normal, the pain, and soreness with tren?
