is a small air bubble in the barrel a problem subcutaneously
i have eight sites and an eight week rotation. it is written on the fridge
pinch
is 31G noticeably better than 29G or is it marginal
drawing up with the same pin you inject with is fine, it just dulls the tip slightly
do you use the insulin syringe for both drawing and injecting
😂1
absorption differences between subcutaneous sites are small for a weekly compound
i inject the back of my own arm and it is awkward but doable with a mirror
31G 8mm for everything. i tried the 12.7mm once and never went back
warming the vial in your hand for a minute is the cheapest comfort improvement there is
a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
do you count to five before withdrawing
a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it
coming back to this whats your sharps disposal setup, mine is a jar and i know thats wrong

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

try the thigh

90 degrees or 45
do you change the pin between drawing up and injecting
bleeding a little means you nicked a small vessel. it is not a technique failure
a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
do not reuse pins. it is not about sterility so much as the tip being blunt after one pass
cold from the fridge genuinely stings more. i let it sit out for ten minutes
push slowly. fast is what causes the ache afterwards
do not aspirate for a subcutaneous injection, there is nothing to aspirate for
abdomen two inches out from the navel, avoiding anything that has been injected in the last month

small bubble is fine
i keep the sharps bin next to the fridge so the whole thing happens in one place
a proper sharps bin costs almost nothing and pharmacies will take it back

unrelated but never recap a used pin. that is how people stick themselves
the needle went in fine but it stung going in, alcohol or the compound

pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising
90 degrees works fine if you have the tissue for it. 45 if you do not
coming back after 9 months, has the pinned technique guide changed
thats a reaction
welts at the site are usually a mild local reaction and rotation sorts it, thats just me
update from 15 months ago: switched to a fixed rotation and the site reactions stopped, i think
sorry to jump in i keep getting a small welt at the site, technique or reaction
