Highlights from this day
  • salt_bridge — is 31G noticeably better than 29G or is it marginal 22:29
  • invoice_mismatch — genuine question anyone inject in the back of the arm on their own successfully 22:48
  • invoice_mismatch — do you count to five before withdrawing 23:41

do you pinch or stretch

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

31G in 8mm or 12.7mm for abdomen

welts at the site are usually a mild local reaction and rotation sorts it

45 degrees

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

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

SB

coming back after 14 months, has the pinned technique guide changed

pinch

follow up cold from the fridge genuinely stings more. i let it sit out for ten minutes, ill dig out the number

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

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

SS

warming the vial in your hand for a minute is the cheapest comfort improvement there is, still working it out

IM

the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small

SS

a proper sharps bin costs almost nothing and pharmacies will take it back

SD

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

SD

absorption differences between subcutaneous sites are small for a weekly compound

i bled a bit, is that a needle depth thing

SD

drawing up with the same pin you inject with is fine, it just dulls the tip slightly

SD

slightly off topic but pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising

do you count to five before withdrawing
