Highlights from this day
- lena_lots — coming back after 14 months, has the pinned technique guide changed 20:41
- still_here_2024 — bleeding a little means you nicked a small vessel. it is not a technique failure 21:29
- cedar_counts — anyone inject in the back of the arm on their own successfully 22:13
- pinch_not_stretch — abdomen two inches out from the navel, avoiding anything that has been injected in the last month 23:16
the needle went in fine but it stung going in, alcohol or the compound
does the injection site matter for how quickly it hits
thigh or abdomen, does absorption actually differ

⚠️12❤️15🙏1
pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising
i mark the rotation in a notes app because the marks fade and i lost track twice
i inject the back of my own arm and it is awkward but doable with a mirror
pinch
😂1🧊6
how do you avoid hitting the same spot twice when the marks fade
[edited]slightly off topic but how many sites are in your rotation
not a problem
update from 8 months ago: switched to a fixed rotation and the site reactions stopped
*VendorInvestigate not the other one
push slow
[edited]do not aspirate for a subcutaneous injection, there is nothing to aspirate for
is there any reason to warm the vial in your hand first
rotate

thats normal
thats a reaction
i bled a bit, is that a needle depth thing
is bruising more about the needle or the aftercare
anyone got a rotation map they would share
bleeding a little means you nicked a small vessel. it is not a technique failure

mark it down

fresh pin
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
follow up 31G 8mm for everything. i tried the 12.7mm once and never went back
if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle
absorption differences between subcutaneous sites are small for a weekly compound, take that with a pinch of salt
never recap a used pin. that is how people stick themselves

cold from the fridge genuinely stings more. i let it sit out for ten minutes
i changed nothing except letting the swab dry and the stinging stopped completely
a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it, happy to be corrected

45 degrees

try the thigh
i have eight sites and an eight week rotation. it is written on the fridge

small bubble is fine

let it dry
push slowly. fast is what causes the ache afterwards
warming the vial in your hand for a minute is the cheapest comfort improvement there is
dont recap
sharps bin
how slowly should you actually push
does injecting a cold vial hurt more or am i imagining it
welts at the site are usually a mild local reaction and rotation sorts it
[edited]90 degrees or 45

90 degrees works fine if you have the tissue for it. 45 if you do not
do you count to five before withdrawing
[edited]warm it first
is 31G noticeably better than 29G or is it marginal
