#injection-technique 2026-06-11

update on the earlier thing do not reuse pins. it is not about sterility so much as the tip being blunt after one pass

while im here i inject the back of my own arm and it is awkward but doable with a mirror
i changed nothing except letting the swab dry and the stinging stopped completely

31G 8mm

i keep the sharps bin next to the fridge so the whole thing happens in one place, ill dig out the number

absorption differences between subcutaneous sites are small for a weekly compound

warming the vial in your hand for a minute is the cheapest comfort improvement there is

a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call

pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising

30G in 8mm or 12.7mm for abdomen

let the alcohol dry. that is ninety percent of "my injections sting"

cold from the fridge genuinely stings more. i let it sit out for ten minutes

rotate

whats your sharps disposal setup, mine is a jar and i know thats wrong

is 31G noticeably better than 29G or is it marginal
do not aspirate for a subcutaneous injection, there is nothing to aspirate for

push slowly. fast is what causes the ache afterwards

is there any reason to warm the vial in your hand first

thats a reaction

a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it

do not aspirate for a subcutaneous injection, there is nothing to aspirate for, ask me again in a month

unrelated but if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle

how do you avoid hitting the same spot twice when the marks fade

mark it down

welts at the site are usually a mild local reaction and rotation sorts it

i bled a bit, is that a needle depth thing

does the injection site matter for how quickly it hits

sorry to jump in do you count to five before withdrawing
