If the affected area is hot and lumpy you might be introducing bacteria to the area. Usually the hot and red tint to an area like that means infection. I am not sure iif I read this right but it looks like you are using the same pin for 5 shots. Now if those shots are consecutive then it wouldn't be a problem but if you wait a couple hours before the next injection then bacteria has had a chance to settle on the needle thus introducing it to the inside of your body. There are many things that could be going wrong right now so you will just have figure these things out. Make sure to try and use a sterile technique when injecting.
