Highlights from this day
  • week_zero — push slowly. fast is what causes the ache afterwards 15:44
  • spreadsheet_stu — a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call 16:01
  • apob_over_ldl — follow up how far from the navel is actually far enough 17:21
  • electrolyte_eli — unrelated but the needle went in fine but it stung going in, alcohol or the compound 18:03

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

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

abdomen two inches out from the navel, avoiding anything that has been injected in the last month

does injecting a cold vial hurt more or am i imagining it

LT

slightly off topic but i changed nothing except letting the swab dry and the stinging stopped completely

NP

does the injection site matter for how quickly it hits

31G in 8mm or 12.7mm for abdomen

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

NP

do you use the insulin syringe for both drawing and injecting

right so 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

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

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

do you aspirate, or is that only an intramuscular thing

while im here is a small air bubble in the barrel a problem subcutaneously

anyone inject in the back of the arm on their own successfully
welts at the site are usually a mild local reaction and rotation sorts it

update from 2 months ago: switched to a fixed rotation and the site reactions stopped
