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

Highlights from this day
- snac_and_water — do not reuse pins. it is not about sterility so much as the tip being blunt after one pass 19:15
- thirty_one_g — drawing up with the same pin you inject with is fine, it just dulls the tip slightly 20:02
- pia_plateaus — genuine question anyone inject in the back of the arm on their own successfully 21:22
nobody here should be telling you where to inject. we can tell you what we do, anyway
mark it down
a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it
pinch
do not aspirate for a subcutaneous injection, there is nothing to aspirate for

whats your sharps disposal setup, mine is a jar and i know thats wrong
is there any reason to warm the vial in your hand first
anyone got a rotation map they would share
unrelated but if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle

how do you avoid hitting the same spot twice when the marks fade
31G 8mm

update from 10 months ago: switched to a fixed rotation and the site reactions stopped
thats normal
warming the vial in your hand for a minute is the cheapest comfort improvement there is
i keep getting a small welt at the site, technique or reaction
drawing up with the same pin you inject with is fine, it just dulls the tip slightly

genuine question abdomen two inches out from the navel, avoiding anything that has been injected in the last month
i keep the sharps bin next to the fridge so the whole thing happens in one place
quick one is bruising more about the needle or the aftercare

sorry to jump in do you change the pin between drawing up and injecting
cold from the fridge genuinely stings more. i let it sit out for ten minutes
31G 8mm for everything. i tried the 12.7mm once and never went back
i inject the back of my own arm and it is awkward but doable with a mirror
do you use the insulin syringe for both drawing and injecting
a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
absorption differences between subcutaneous sites are small for a weekly compound
genuine question anyone inject in the back of the arm on their own successfully

ok so i have eight sites and an eight week rotation. it is written on the fridge
the needle went in fine but it stung going in, alcohol or the compound
90 degrees or 45
i mark the rotation in a notes app because the marks fade and i lost track twice, ask me again in a month
push slowly. fast is what causes the ache afterwards
let it dry
