Highlights from this day
- eight_mm — a proper sharps bin costs almost nothing and pharmacies will take it back 20:19
- mira_pins — does injecting a cold vial hurt more or am i imagining it 20:29
- appetite_back — 31G 8mm for everything. i tried the 12.7mm once and never went back 21:26
- sgp_subq — the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small 22:43
fresh pin
mark it down
a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it
warm it first
try the thigh
a proper sharps bin costs almost nothing and pharmacies will take it back

rotate
abdomen two inches out from the navel, avoiding anything that has been injected in the last month

technique probably
[edited]do you aspirate, or is that only an intramuscular thing
sharps bin
bleeding a little means you nicked a small vessel. it is not a technique failure
anyone got a rotation map they would share

if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle
45 degrees
slightly off topic but pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising

warming the vial in your hand for a minute is the cheapest comfort improvement there is
thats a reaction
push slow
the needle went in fine but it stung going in, alcohol or the compound

coming back to this how many sites are in your rotation
i have eight sites and an eight week rotation. it is written on the fridge
do you pinch or stretch
welts at the site are usually a mild local reaction and rotation sorts it
while im here thigh or abdomen, does absorption actually differ
dont recap

thats normal
update from 26 months ago: switched to a fixed rotation and the site reactions stopped
cold from the fridge genuinely stings more. i let it sit out for ten minutes
follow up welts at the site are usually a mild local reaction and rotation sorts it, from memory
does the injection site matter for how quickly it hits
pinch

do you change the pin between drawing up and injecting
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small

nobody here should be telling you where to inject. we can tell you what we do
small bubble is fine
do not aspirate for a subcutaneous injection, there is nothing to aspirate for
update from 19 months ago: switched to a fixed rotation and the site reactions stopped
while im here coming back after 2 months, has the pinned technique guide changed
i keep getting a small welt at the site, technique or reaction
