Hard lump and slight bruise at injection site

[DaveT81]

Hi all, been SI for about 12 months now and, apart from the occasional bit of slight pain, I've never had any issues.

This morning, injecting as usual, I pulled back the plunger - no blood - but about half-way through I noticed I had tilted the syringe/self-injector device slightly to the side without realising.

Upon pulling out the syringe, blood poured out. Stopped within 10 seconds and I cleaned it up and put a plaster on but I immediately had a hard lump.

I have to admit, I'm a bit concerned now. Is this something that can happen? I've obviously nicked a blood vessel and I'm thinking that, with the syringe tilted, I may have injected a little higher than usual and now the B12 has pooled there?

Pic attached below. You can't really see the lump but it's definitely there! I've seen a few posts talking about the red liquid pooling beneath the surface but this is blue, so unsure whether it's bruising. I'd assume so though.

FYI I inject subcut, not IM. But never had this issue before.

I think it's fine. If you massage it or put a warm flannel it should disperses any b12 pooled there The blue is most likely a bruise from the bleed.

I do subcutaneous b12 too.

My husband has had the same as you as Injects insulin sc.

I showed him youf photo.

So a warm compress

The later a cold one fof bruising

I'm not medical but this is our experience.

Get a medic to look if still concerned.

Horrid

Thanks! I'll do that now. Hopefully it'll recede over the next 24 hours.

Appreciate the advice too, as I am a bit concerned.

I frequently got lumps and bruises when I tried to inject into my thighs, so I gave up. Now I usually have my partner do them for me, IM in arms and SC in back and stomach. (I used to do IM in hip but hit a nerve once and it scared me for a couple weeks.) Those lumps and bruises can take quite a while to go away but they do eventually. 🙂
