Input: Text: we were sitting on a beach at a local river, i wanted to  catch some sunset shots over the water with my camera. i was sitting next to him waiting for the light to get right (forest fires here all over make killer sunsets) when he all of a sudden jumps up to chase something and so i instinctively grabbed his collar. i should mention that me grabbing his collar had little effect mostly 'cause he's a 160+ pound bullmastiff. i also didn't let go meaning he pulled my arm right out of the socket.  

it did not wanna go back in. i tried various ways to stretch and pop it but that was just pure pain. i could feel the tendons stretching out when i fucked with it. the bones grinding together, you get the idea. not happening.  

so i call a buddy, "hey you know how to put a arm back in the socket?"  "ya grab on something and pull opposite real hard.  but if you fuck up you will need surgery. prolly better go in."    

ok, i'm doing that i'm going in. i call another friend and ask her to figure out where to go from where i am, at this point doggo and i are headed to he car. i have my right upper arm sort of resting on my ear, with my forearm on top of my head. i've been like this for fifteen minutes or so. it isn't awful pain except when i move it. it's about 3/4 mile or so back to the car. i'm walking with my arm wrapped over my head, doggo on leash in other hand.   

oh yeah, about my dog. he is officially the best dog ever. as soon as he realized what happened, he stopped dead and came right back to me and he wasn't leaving. another dog came up and my boy just stood there and ignored the other dog, getting between me and it and he stuck by me on the way back to the car. he knew i was hurt.  

we get back to the car, loaded up the dog, i get in, my friend calls and tells me where to go, texts me address. fuck it's 23 minutes. fuck it's gotta be er not urgent care. fuck i have to drive myself there. i make it, get checked in and the wait begins.... 5ish hours before seeing a doctor. x-rays suuuuuuuuuuuuuucked. it got to the point where i asked for pain meds but they take their time with that anymore. you know what? fuck it. i'm glad they do it that way.  sitting here, fucking arm still wrapped around my head. i'm relatively certain i walked past someone in that er who was there to score meds and nothing else. i'll take a little pain to support a putting wrench in that little game. if i had really played it off i would have got em sooner i'm sure, if it was that bad. 

and it did get pretty bad, by the time the doc was free enough to see me they had an iv in (approaching hour six) and ready for 200mg fentanyl and no clue how many mg of some other shit that knocked me right out out temporarily. i woke up with no arm over my head and high as fuck. i did end up with a light prescription but no pharmacies are open, yay!!!    i got gummies at least, i'm good.

TIFU by taking my dog to the beach; ended up driving myself to ER with dislocated shoulder.
