he reuses the same needle so many times? each time tip penetrates, i thought it dulls a bit and that has to hurt.... i feel like at many points he can easily hit bone? wouldnt bone hurt a fukton to hit with a needle?

ive been thinking about this for my shoulder but holy shit, id ask for some numbness injected into shoulder first, dafuk, i would fidget around and move just cause and spasm like twitch my shoulder due to a fukin needle so often ....

he like bobs the needle up and down as it goes in too ?

Turned it off after he started talking because I'm at work and I didn't want his voice to put me to sleep.

Tattoo artists use the same needle 10,000 times an hour

completely different as far as i know

hes very generally providing a bunch of intramuscular, subcutaneous and intracapsular injections. shit will get everywhere, but as long as hes being careful with depth you'd be surprised at how deep the humerus actually is in the shoulder, other than that the clavicle is easy to landmark so he just has to worry about the scapular spine really. theres a solid inch of tissue at least in most areas of the GH joint, he can be fairly liberal with that stuff.

needles have to puncture a lot of different densities of tissue, youd be surprised how tough some fascia is. if youre comparing that vid to antecubital venous draws theyre much much different. ive had to insert needles into my own hand and a few triceps and calves now and its tough, you have to actually use some force

e: and its not really weird that hes using the same needle for every puncture, if he cleaned the entire area with alcohol and is only using gloves, the entire procedure is deemed "clean" (not sterile, that has a strict definition) but really you aren't doing anything weird by removing the needle and replacing it in a slightly different location

this all sounds legit but i'm wondering why you were sticking needles into yourself



yeah dude i am scared of needles. i had a vaccination booster last year and was pleasantly surprised that i literally did not feel it. i was scared like a bitch

Experiments in my lab. We study nerve and muscle physiology so I had to stick a needle into one of my palm muscles for someone's pilot testing

E: he just didn't want to hurt me too much so I did it myself

i dont mind needles too much but just how rough hes being and the area just seems sketchy



oh yeah thanks for the explanation previously

but holy shit a class requires u to stick a needle in urself... even if its legit reason holy shit lol

also from the your previous post, i understand muscle and stuff can be tough, so u steadily push needle in. but hes like jiggling it around, im assuming its so the solution is spread as he jiggles it, so not just one spot? cause that seems like a weird technique. i guess he is purposely damaging the area by not just doing a straight line insertion?

no its not a class, its the lab that I work in. I take classes within my degree but I essentially spend 2 years working for my supervisor and conducting research for him. everything is very clean in the lab, we clean the skin before breaking it and autoclave the needles then douse them in alcohol to make sure nothing infects. hes likely using a relatively flexible needle, and wiggling it just so it goes in easier. I could be wrong, and there probably is some spreading of the solution around when he does that but it looks like hes just trying to get the needle through tough tissue

ok thanks

sounds interesting and bit extreme lol

by me. i normally have lecture classes separate from lab classes. in labs we do stupidly basic experiments on a very small scale. thats why i assumed lab meant class
