I've done my first two T injections now (weekly subq of test c), last Thursday and this Thursday just gone. I've just noticed while in the shower that around the most recent injection site on my belly there's a red patch (and the skin under it feels a bit harder almost like a lump), and on the previous one there's a small bruise with a little bit of bruising going down from it. Just wanted to check if this is anything to be concerned about?

Neither injection hurt in any way, and the spots aren't hot or painful in any way, and I don't feel unwell or anything. I used alcohol wipes to clean the vial and the injection sites, and there's no sign of infection. I use an auto injector for the injection cause I'm not good with needles.

I do have pretty sensitive skin. When I had my hysto last year and had to have a blood thinner injection daily for a week after it left a little bruise every time, but no noticeable redness, and the bruises were smaller despite a larger needles and larger volume of stuff being injected.
