Sunday39 messages10 participantstimes are UTC
Highlights from this day
  • luerlok — welts at the site are usually a mild local reaction and rotation sorts it 12:31
  • month_six_me — the needle went in fine but it stung going in, alcohol or the compound 13:13
  • luerlok — do not reuse pins. it is not about sterility so much as the tip being blunt after one pass 15:27
  • luerlok — slightly off topic but the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small 16:04
  • subq_sy — i keep the sharps bin next to the fridge so the whole thing happens in one place 16:17

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

RT

cold from the fridge genuinely stings more. i let it sit out for ten minutes, thats just me

is there any reason to warm the vial in your hand first

UD

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

is a small air bubble in the barrel a problem subcutaneously

do you count to five before withdrawing

how do you avoid hitting the same spot twice when the marks fade

bleeding a little means you nicked a small vessel. it is not a technique failure

TO

i inject the back of my own arm and it is awkward but doable with a mirror

SS

nobody here should be telling you where to inject. we can tell you what we do, n of 1 obviously

right so absorption differences between subcutaneous sites are small for a weekly compound

small bubble is fine
