Highlights from this day

no_appetite_nia — do not reuse pins. it is not about sterility so much as the tip being blunt after one pass 10:33
cold_start_cy — while im here i mark the rotation in a notes app because the marks fade and i lost track twice 11:05
first_and_last_four — i keep the sharps bin next to the fridge so the whole thing happens in one place, thats one data point 12:07
hair_month_four — a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call 12:10

warm it first

wk1 L abdo upper   wk5 L thigh outer
wk2 R abdo upper   wk6 R thigh outer
wk3 L abdo lower   wk7 L arm back
wk4 R abdo lower   wk8 R arm back

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

i changed nothing except letting the swab dry and the stinging stopped completely

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

mark it down

thats normal

while im here i mark the rotation in a notes app because the marks fade and i lost track twice

rotate

is bruising more about the needle or the aftercare

i keep the sharps bin next to the fridge so the whole thing happens in one place, thats one data point

how far from the navel is actually far enough

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

[edited]

how slowly should you actually push

let the alcohol dry. that is ninety percent of "my injections sting", thats one data point

coming back after 26 months, has the pinned technique guide changed

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

do not aspirate for a subcutaneous injection, there is nothing to aspirate for

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

thats a reaction

bleeding a little means you nicked a small vessel. it is not a technique failure
