Can you do subcut injection without pinching up skin?

Hello everyone!

Previously, I have performed IM self injections. This has largely been fine and unproblematic, but a painful incident on the most recent attempt made me want to seek alternatives.

I'm sure SC injections might be nicer for me as the needle is smaller and a lot of people on this forum report less pain.

The problem is, I am very thin, and cannot pinch up much skin on my thigh or belly. I am also hesitant to use a technique (pinched skin and 45 degrees) without having a nurse to teach me and check I'm doing it right (a nurse originally showed me how to do IM 90 degree injections into my outer thigh).

As far as I can tell, the reason for pinching the skin of your thigh is to avoid hitting muscle. But B12 can be injected into muscles as this is what you do with IM injections. So could I just use the normal IM injection technique but with a smaller SC needle? I think this would be easier for me psychologically.

Hi Mereri, if you are going to do SC into the tummy, then it's best to pinch. You can see how they do in this video at around time 7 minutes 30 seconds youtube.com/watch?v=fkBuY4i... Even if you can't pinch much skin/fat, they do into the side part. But still at 90 degrees. I too would not do 45!

If you are going to do SC on your thigh, then I see no reason why you can't do it like IM - no pinching. Just remember that it might sting - I've noticed that IM never stings but SC can for sure do that - due to the nerve endings on the skin I guess.

Good luck!

That video seems over complicated compared to a single use b12 vial.1. Wash hands and have a clean surface.

2. Snap off top of ampoule

3. Draw up all the b12 with one needle say 21G

4 Remove that needle and put in sharps box

5 put on needle to inject

6. Flick the side if any air bubbles

7. Hold flesh

8 inject at a speed comfortable

9. Count to 10

10. Remove needle

Clear up putting all sharps in a sharps bin.

It rarely stings like IM injections like IM rarely stings . I have both.

A tip is to make sure b12 is at room temperature and to relax.

I breath out .

You will find s way that suits you .

I've never done an IM b12 .

A nurse does it

Thank you for the help!

I don't know why the thought of pinching freaks me out so much but it just does. I think because I usually like to have both hands on the needle whilst injecting to keep it very steady.

It seems most people agree IM technique into the thigh would be fine. Your stinging comment is intriguing. From what I observed, the general anecdotal consensus on these forums have been that SC is less painful than IM.

Hi Mereri,

I had the exact same problem as you, where I was not able to pinch up skin to do a SC injection as recommended. My solution was to purchase 4mm needles which do not necessitate pinching of skin - these work fine for me.

Best wishes

Mereri in reply tojeremycat_

4mm sounds wonderful. Can you still inject the full 1 ml dose? where do you buy yours from?

jeremycat_ profile image
jeremycat_ in reply toMereri

Yes you can still inject 1ml as they just fit onto the same syringes as other needles. Here is the link I buy from: ukmedi.co.uk/27g-grey-4mm-m...

The usual sub- cutaneous needle is 1/2 inch ( 12.7 mm)

“There is an insulin syringe with a fixed needle of 8 mm but the syringe is only 0.3 ml so not much use to you if you are using 1ml ampoules .

There is a way to measure the thickness of your fat layer ( google)!

You can self-inject subcutaneously into your tummy fat , or the front of your thigh . So you need to use the fattest place .

Certainly subcutaneous injection looks far less intimidating than I.M ,as the needle is much shorter and finer .

When I started sc b12 injections I was thin.Had no problems.

Unless you are very very thin most havd a Small bit of flesh to hold together on your stomach 2" away from belly button.

Outer thighs also.

J use a 1/2 " long needle 30 G

27-30G suitable.

Havd been doing this for over 2 years with a IM one 6 weekly .

Always hoping IM will last longer.

For me they don't.

Do have effects quicker but seem to give mord of z seesaw effect.

Worth s try for you

Hi Nackapan, great info for Mereri and all of us on here - thank you. I'm just plucking up courage to start SI - will do subcut as I find the IM by nurse very painful, again might be like Mereri a bit thin on the padding! Have managed to get some ampoules from the German website many of you use, and just about to get an order in for equipment from Medisave. This is the syringe I was thinking of ordering, it's a combined all in one - is that ok? Link as follows and would value opinions please before I order:

Great to have the video too. All info is power to our elbows!

I find it very difficult to draw from the ampoule using a fixed needle syringe..the needle is too short... they are also very expensive.I order 2ml syringes

30g injecting needle

23g drawing up needle

From Medisave.co.uk...about £13 ?for 100 of each including postage

Thank you Lincsangel1, I am totally new to SI so appreciate any information about the basics that are needed. I'll look at your suggestions - thanks again.

Lincsangel1 in reply toJanCymru

I've just checked..and the ones on your link are no good as they are only 0.3ml...ampoules are either 1ml or 2ml depending on brand... so they wouldn't be any good, as well as not being long enough to draw up the B12

Thanks Lincsangel1, appreciate all the information, am a complete novice so finding my way forward at the moment and obviously want to ensure the purchase is relevant!

Nackapan profile image
Nackapan in reply toJanCymru

That's fine if you are very careful not to blunt the needle touching the inside of the ampoule.I chose to use one needle for drawing up b12 21G

Then change needle to inject

30G

Can use 27-30

Hi Lincsangel1, Have got the B12 ampoules - Vitamin B12 Depot 1mg/1ml from Apothe.de the German pharmacy recommended on here by most folk.

I do SC everyday. I use insulin needles - 6mm 31G 1ml. I only inject some 0.2ml, as I think a lower dose is better and about 50-100mcg/day is more than enough and I found the lower dose (50mcg) better actually. It is very simple and does not sting at all. I think the key is to use a smaller and thinner needle and as low a dose as possible. With 4-6mm, there is no possibility of hitting muscle even for a thin person, so you should be fine.

Great explanations from Nackapan. I use a very thin 1/2 inch 30 G second needle to inject subcutaneous. Straight in , you can pinch but not necessary. It might sting a bit if like Nackapan says the liquid is cold or a drop of it is sitting on the tip of the needle. I sit down and relax the leg I inject into.

Ok wonderful! Just wanted to check that injecting into thigh (without pinching) at the usual 90 degree angle was fine. I couldn't think of a good reason why it wouldn't be. Do you use a 45 degree angle or 90 degrees?

Both I think
