Doing my 1st Delt INJ after 3 years of giving delts time off. Vids show that 2 Nerves

[NiceGuyResearcher]

Hi

Im Doing my 1st Delt INJ after 3 years of giving delts time off. Vids show that 2 Nerves right near the center of the delt site can be problematic

i mean,here i am Brushing up Hopeful Bright eyed bushy tailed only to find in horror 2 nerves one axial up and down and one other nerve left to right very close to that rectangular spot or the Inverted triangle, you see in spot injections

Some of these recent vids i've watched in a day or so to brush up on my delt im inj skills or to remind me how to do them, said the Delts no longer need aspirating as the medical community has deemed them free of major blood vessels, etc, that's kind of hard for me to believe, I'd rather Err on the side of aspirating

Anyway, these 2 nerves can actually cause paralysis that may not be something that can "resolve" is what they call it in medical jargon and they use such phrases and terms of art as "frozen shoulder," Months of a weakness and poor range of motion

The vids mentioning nerves in the area are produced on ytube by a Medical Doctor, so i'm guessing he may have an incentive to keep IM injections mysterious and done only by licensed pro's like a Nurse?

Or...should I not worry and measure 3 finger lengths from the top boney part of either deltoid Downward and inject right dead center and aspirate?

The last thing i want is to hit a nerve-- as an aside, 1 friend in 2003, hit a nerve in his glute and was temporarily paralyzed for several days

thanks in advance for maybe some reply or advice like don't overthink this...right in the center obviously not too high wherer the shoulder bone is and not too low where ur nearer to the elbow, the 2 or 3 fingers horizontally placed and underneath them, right in the center is a good spot ?

thanks again
