do not reuse pins. it is not about sterility so much as the tip being blunt after one pass, n of 1 obviously

Highlights from this day
- sharps_bin_sid — if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle 16:18
- appetite_back — welts at the site are usually a mild local reaction and rotation sorts it never recap a used pin. that is how people stick themselves 17:35
- van_isle_vial — do you aspirate, or is that only an intramuscular thing 17:48
warming the vial in your hand for a minute is the cheapest comfort improvement there is
small bubble is fine
90 degrees works fine if you have the tissue for it. 45 if you do not
update from 25 months ago: switched to a fixed rotation and the site reactions stopped, we shall see
is bruising more about the needle or the aftercare

nobody here should be telling you where to inject. we can tell you what we do, thats just me
sorry to jump in a proper sharps bin costs almost nothing and pharmacies will take it back
i keep the sharps bin next to the fridge so the whole thing happens in one place, for what its worth
45 degrees
update on the earlier thing do you pinch or stretch
never recap a used pin. that is how people stick themselves
anyone got a rotation map they would share

genuine question i have eight sites and an eight week rotation. it is written on the fridge
lead_time_larssorry to jump in a proper sharps bin costs almost nothing and pharmacies will take it…
absorption differences between subcutaneous sites are small for a weekly compound
i mark the rotation in a notes app because the marks fade and i lost track twice
do you count to five before withdrawing
not a problem

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

coming back after 19 months, has the pinned technique guide changed
queue_positiondo not reuse pins. it is not about sterility so much as the tip being blunt after one…
thigh or abdomen, does absorption actually differ
31G 8mm for everything. i tried the 12.7mm once and never went back
i inject the back of my own arm and it is awkward but doable with a mirror
do you use the insulin syringe for both drawing and injecting
if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle

how many sites are in your rotation
📈2
sharps bin
bleeding a little means you nicked a small vessel. it is not a technique failure
push slowly. fast is what causes the ache afterwards
pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising

a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call, from memory
let the alcohol dry. that is ninety percent of "my injections sting"
dont recap
welts at the site are usually a mild local reaction and rotation sorts it
never recap a used pin. that is how people stick themselves

how far from the navel is actually far enough
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
does injecting a cold vial hurt more or am i imagining it
is a small air bubble in the barrel a problem subcutaneously
drawing up with the same pin you inject with is fine, it just dulls the tip slightly
*Janoshik not the other one
let it dry
technique probably
do you aspirate, or is that only an intramuscular thing
