Highlights from this day
- taper_or_not — 31G 8mm for everything. i tried the 12.7mm once and never went back 21:57
- bea_reconstitutes — do you count to five before withdrawing 22:42
- bea_reconstitutes — is 31G noticeably better than 29G or is it marginal 22:57
- dexa_or_bia — cold from the fridge genuinely stings more. i let it sit out for ten minutes 23:02
- yyz_vial — i inject the back of my own arm and it is awkward but doable with a mirror 23:08
coming back after 23 months, has the pinned technique guide changed
follow up how do you avoid hitting the same spot twice when the marks fade
⚠️1
technique probably
pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising
i keep the sharps bin next to the fridge so the whole thing happens in one place
do not aspirate for a subcutaneous injection, there is nothing to aspirate for
thigh or abdomen, does absorption actually differ
i mark the rotation in a notes app because the marks fade and i lost track twice
update from 11 months ago: switched to a fixed rotation and the site reactions stopped, i have it written down somewhere
is a small air bubble in the barrel a problem subcutaneously
bleeding a little means you nicked a small vessel. it is not a technique failure
push slowly. fast is what causes the ache afterwards

if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle
abdomen two inches out from the navel, avoiding anything that has been injected in the last month
does the injection site matter for how quickly it hits
29G in 8mm or 12.7mm for abdomen
do not aspirate for a subcutaneous injection, there is nothing to aspirate for
do not reuse pins. it is not about sterility so much as the tip being blunt after one pass, take that with a pinch of salt
i changed nothing except letting the swab dry and the stinging stopped completely

do you count to five before withdrawing

a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
not a problem
45 degrees
is 31G noticeably better than 29G or is it marginal

anyone inject in the back of the arm on their own successfully
👍4🙏1⚠️1
coming back to this do you change the pin between drawing up and injecting

do you pinch or stretch
absorption differences between subcutaneous sites are small for a weekly compound
follow up warming the vial in your hand for a minute is the cheapest comfort improvement there is
pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising
fresh pin
