I didn’t want to start a new thread since my issue is a bit similar to the OPs.
I’m currently running a Cyp/EQ cycle and I did a delt injection on Saturday. No problems Saturday, Sunday, or Monday. Yesterday my medial delt felt kind of sore but I worked out anyway (Chest). Afterward it looked like my delt was a bit swollen and later in the day it was swollen throughout the entire medial delt, not just near the injection site.
Overnight some of my skin has gotten pink/light red, but it’s at least 4 inches down from where I injected myself, nowhere near the origin. No fever, there’s no heat/warmth in comparison with the other side, and pressing my finger anywhere on the delt doesn’t leave any imprint. My shoulder doesn’t hurt, it just is a bit hard to move due to the swelling and feels kind of like I have a charlie horse if I move my arm laterally.
I’m probably going to head to Urgent Care when I have a chance later tonight though. My insurance won’t cover any of this since I just have catastrophic, so I know I’ll be out a decent amount if I go in (I’d rather be out money than a medial deltoid though).
I know you don’t need all symptoms for it to be an infection, it’s just weird that the swelling didn’t even start until the 4th day and it wasn’t until after I worked out. Plus the pink/light red coloration isn’t even near the injection sight but is near the insertion of the delt, more near where the tricep and bicep meet.[/quote]
You documented your positive symptoms and relevant negatives well - kudos.
Certainly injecting regularly makes one suspicious of an abscess first thing, but the distance from the injection site combined with the proximity to the muscle insertion makes one think it could be some sort of musculoskeletal flare up, especially if the pain became evident a few hours after working out.
The lack of an imprint in the skin when pushing on it does not indicate its not an abscess. An abscess, if anything, will rebound the skin faster, somewhat similar to a water balloon. You could give it more time, or you could go into the urgent care clinic. It all depends on how sick you feel you are. Caution is always the best route for someone who has not had or seen many abscessed before, they can become quite serious. If you feel sick, or like the pain is more profound than a simple injury, go in to casualty and don’t let any internet doctor dickhead tell you otherwise.
Depending how deep the abscess is, you can try and transilluminate it. This involves getting a small torch and shining it at point blank range against the skin, on an angle. If it is an abscess, and it is superficial enough, the fluid inside the cavity will glow red. Google search the word to get an idea of what it looks like.
If this test is negative, it should not serve to discourage you from attending casualty, it is not to be used to rule out an abscess. If it is positive, it should most certainly encourage you to go, as it quite a specific test.
