I’d try it if they would pay. (and I mean paying out good as well…not some $5 bullsh!t…)

I don’t think I’d ever be able to donate blood. I’m nervous around needles at the best of times, and the thought of that amount of blood – y’know, the really important stuff you always want to keep inside your body – being drawn out of me… just, fuck it, I ain’t doing it. I do think that donating blood is a good and selfless thing to do, but you’ll pardon me if I remain a vocal supporter of it rather than a practical one.

@Alara Rogers  
The world is far from ever needing my blood.

If one did not see the line on the paper about the parallel universe thing, you could have possibly made the assessment that donating blood slowly turns you into a pony.
 
 
Using said logic, you could craft a fanfic where some sort of deus ex machina has tampered with the blood donation equipment, and from this picture you could say Derpy has just started, Vinyl is about two-thirds through, and Octavia has finished giving blood, and is now 100% pone.
 
Meanwhile, Nurse Rarity is confused why all her patients keep turning into ponies on her and is starting to freak out, and wondering whether she can still use the blood donated. Discord, meanwhile, has picked up on extra-dimensional pony energy and has come to investigate, but now is having too much fun watching the transformation chaos, snapping photos to share with Fluttershy at their next tea party (and his personal collection). :3

It does sound like we have the same thing. One of the times it happened, I was fasting, and the other two I was hungry at the time. All three times, I was sitting up, and when I started lying down during blood draws, I didn’t have any problems.

@Phantom Rider  
And Twilight raises a good question. Whose blood is compatible with whose? It’s one of those things you really can’t afford to get wrong.

@WatermelonRat  
It is not psychosomatic.
 
I have the same condition. I acquired it when I was 12. No problem with blood draws prior to that. I had a fasting blood draw done to test me for hypoglycemia, and I watched the nurse do it because biology fascinates me, and I had no problem. But I passed out ten minutes later. After that, a few months later at the pediatrician, I told the phlebotomist “Oh, funny, the last time I had this done I passed out.” She was alarmed (I wasn’t, I thought I was joking) and asked if I was going to do it again. I said, “Well, we’ll just have to see, right?” And then passed out.
 
Since then, if I have blood drawn from my elbow while I’m sitting up, I will pass out, or convulse and pass out, and then I’ll throw up. If I am lying down, I usually do not pass out. But it doesn’t happen if the blood is drawn from my hand (which hurts LIKE A BITCH but doesn’t make me pass out) or the middle of my arm. Just the elbow. And it didn’t happen when I was pregnant, when I had higher blood volume.
 
My theory is that those of us who suffer from this have a nerve that’s either too close to the vein or too oversensitive to the signal of blood pressure dropping, right there. Normally if your blood pressure drops very rapidly, you do in fact go into shock. But when your blood is drawn there’s no, or very little, overall blood pressure drop, so you shouldn’t go into shock. However, if the nerve near that vein that detects your blood pressure or venous width or flow speed or whatever it’s detecting to see if you need to go into shock is oversensitive, a local drop right at that spot fools it into thinking you’re bleeding to death. Lying down keeps enough blood going to your head that you stay conscious, and taking it from a different area on your arm (which, let me repeat, HURTS LIKE A BITCH) will avoid the touchy nerve and leave you with no symptoms except that your arm or hand hurts like a mofo.
 
I don’t recommend giving blood, anyway, even if you find that these techniques help you, because I still feel dizzy and shaky even if I was lying down, and I don’t feel as if the world needs my blood badly enough for me to endure the pain in my arms if I get it taken somewhere else. But if you need blood drawn for medical reasons, try having it taken while you’re lying down, or from your hand, and you may find the symptoms a lot more manageable. I almost never pass out anymore and can usually even drive myself home from blood draw appointments.

Nurse Rarity specializes in diagnosing fashion ailments.

I didn’t realize until I read it that yeah, everyone’s drawn differently here! Full pony Tavi, anthro Vinyl, EQG Derpy, full human Rara.

Anyway, I cam here that I’d like to slap Rara’s butt so damn hard to leave a mark on the skirt.

32 time donor. And Jesus Christ, doesn’t anyone donate their blood because there may be someone who needs it?!
 
And I have never had any pain. Even the needle in the vein is nothing more than a nuisance when inserted. Nothing afterwards.  
But I’m a big guy. I know it can be different for others.

@Background Pony #6670  
Your hugs are greatly appreciated. I have an appointment with a new doctor tomorrow, and there’s a significant likelihood that they’ll request a blood test…

@WatermelonRat  

 
Understanding of mine is completely had by you. Hugs are also in order hugs

@WatermelonRat  
Okay, now THAT sucks. You have my sympathies.

Discord’s blood would most likely kill any creature

On three separate occasions, I’ve passed out and gone into convulsions while having my blood drawn. I close my eyes while thinking of something else while they put the needle in, then the next thing I know I’m shaking and drenched in sweat. I don’t know if it’s a psychological thing or if I’m sensitive to losing blood. Whatever it is, I can’t look at this kind of image without wincing.

@Background Pony #6670  
Sorry for the implied imagery and your needle-phobia thing.  
But it does link back to earlier; they’re things that happen and need to be dealt with.  
Like I said, the pain IS NOT GOING AWAY, so I just concentrate on doing the body exercises for the duration.  
In the case of the failed donation; it was recorded as such in my donation history, but at least I still got the free food out of it afterwards.

@Background Pony #54BE  

 
Shit. I myself have just always had a problem with needles. Just seeing a flu shot on TV is enough to make me feel sick in the stomach.

@Background Pony #6670  
Yeah, I’ve had similar: one nurse failed to put the needle in properly resulting in some slight internal bleeding in my usual donation arm (THIS SOUNDS WORSE THAT IT ACTUALLY WAS, WHICH WASN’T THAT MUCH). The result? Purple and yellow discolouration of my skin for around 1-2 weeks afterwards, then back to normal to try donating again a few months later.

@Background Pony #54BE  

 
First time I ever got blood taken, the person taking my blood was a noob. She spent a few minutes fiddling around with the needle in my arm. Needless to say, my dad wanted to beat the living shit out of her lol

@Background Pony #6670  
I wouldn’t call you a weakling, I wouldn’t even call myself particularly ‘strong’ in opposite.  
My view is just that the finger and arm pains I/we feel as part of the procedures are things that HAVE to be ‘gotten over’. Not feeling this pain is (I feel) an impossibility, so I just put up with it as best I can; by concentrating on the muscle movements that supposedly improve blood flow.

@Background Pony #54BE  

 
Pain lasts the whole time the needle is in for me. It may be just that I am a weakling…but they only way that I don’t feel like the blood is being vacuumed out of me painfully is when a pediatric needle is used.

@Background Pony #6670  
some people need blood a lot more than you do

But back to critiquing the art…
 
OMG, it SO detailed! Very well done.

@Background Pony #6670  
19-time donor here. I can attest to this, slightly.  
In my experiences, the only ‘suckage’ I experience is (phase 1) the pain from the needle-prick on the finger (which goes away after like a minute), and (phase 2) the underlying-continuous pain from when the main needle is inserted into the arm and blood is drawn out.
 
TL,DR: I get over it, because free food afterwards.
