- two_eight_c — update from 3 months ago: switched to a fixed rotation and the site reactions stopped pinch, 45 degrees, count to five, withdraw slowly. two years and almost no… 22:55

31G 8mm for everything. i tried the 12.7mm once and never went back
i have eight sites and an eight week rotation. it is written on the fridge
i mark the rotation in a notes app because the marks fade and i lost track twice

how slowly should you actually push
warming the vial in your hand for a minute is the cheapest comfort improvement there is
abdomen two inches out from the navel, avoiding anything that has been injected in the last month
Recon calculator: 40mg in 2ml = 4mg/ml.
do not reuse pins. it is not about sterility so much as the tip being blunt after one pass
i keep the sharps bin next to the fridge so the whole thing happens in one place
a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
do not aspirate for a subcutaneous injection, there is nothing to aspirate for, still working it out
29G in 8mm or 12.7mm for abdomen
thats a reaction
never recap a used pin. that is how people stick themselves, still working it out
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 backpush slowly. fast is what causes the ache afterwards, your mileage will differ
right so cold from the fridge genuinely stings more. i let it sit out for ten minutes
not a problem
bleeding a little means you nicked a small vessel. it is not a technique failure
thats normal
mark it down
welts at the site are usually a mild local reaction and rotation sorts it
update on the earlier thing do you aspirate, or is that only an intramuscular thing
sorry to jump in i changed nothing except letting the swab dry and the stinging stopped completely
do you pinch or stretch
is bruising more about the needle or the aftercare

thigh or abdomen, does absorption actually differ
push slow
pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising
let it dry
