Highlights from this day
- night_pin — 30G in 8mm or 12.7mm for abdomen 12:52
- LC_MS_Lena — i have eight sites and an eight week rotation. it is written on the fridge update from 5 months ago: switched to a fixed rotation and the site reactions stopped 13:22
- endotoxin_ed — warming the vial in your hand for a minute is the cheapest comfort improvement there is 14:45
- two_three_lifts — a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it update from 7 months ago: switched to a fixed rotation… 14:46
- luerlok — do you aspirate, or is that only an intramuscular thing 15:03
let it dry

coming back to this abdomen two inches out from the navel, avoiding anything that has been injected in the last month
31G 8mm

i changed nothing except letting the swab dry and the stinging stopped completely
slightly off topic but the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
45 degrees
[edited]let the alcohol dry. that is ninety percent of "my injections sting", i have it written down somewhere
nobody here should be telling you where to inject. we can tell you what we do
push slow
how slowly should you actually push
31G 8mm for everything. i tried the 12.7mm once and never went back
unrelated but do not aspirate for a subcutaneous injection, there is nothing to aspirate for
30G in 8mm or 12.7mm for abdomen

bleeding a little means you nicked a small vessel. it is not a technique failure
sharps bin
i have eight sites and an eight week rotation. it is written on the fridge
update from 5 months ago: switched to a fixed rotation and the site reactions stopped
i inject the back of my own arm and it is awkward but doable with a mirror
try the thigh
is bruising more about the needle or the aftercare
quick one 90 degrees works fine if you have the tissue for it. 45 if you do not
cold from the fridge genuinely stings more. i let it sit out for ten minutes
[edited]i keep the sharps bin next to the fridge so the whole thing happens in one place
warming the vial in your hand for a minute is the cheapest comfort improvement there is

push slowly. fast is what causes the ache afterwards
thigh or abdomen, does absorption actually differ
how far from the navel is actually far enough
do you aspirate, or is that only an intramuscular thing

update on the earlier thing pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising, someone check my working
