Ok I have a question I was injecting into my glutes and asperated blood pulled out and restuck. The question is that is was swollen for like 4-5 days and like a red bruise i waited it out and it went away but next monday came around and stuck it again but it still feel swollen a little I am not sure if its an infection or whats going on its not really sore at all just like an absest in there or maybe its just me thinking there is. IF anyone has had a infection please tell me symptons. Thanks
