is there any reason to warm the vial in your hand first
welts at the site are usually a mild local reaction and rotation sorts it

if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle

i keep the sharps bin next to the fridge so the whole thing happens in one place

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

do you aspirate, or is that only an intramuscular thing

for the archive 90 degrees or 45

small bubble is fine

update from 11 months ago: switched to a fixed rotation and the site reactions stopped

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

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

45 degrees

31G 8mm for everything. i tried the 12.7mm once and never went back

a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it

nobody here should be telling you where to inject. we can tell you what we do
