"Incorrect use of the needle"

3rd donation in the UK and 3rd time that the nurse assigned to me seemingly does not know how to put the needle in correctly.

The first one i initialy though it was OK but during the donation i could still feel the needle (wich normlay i feel it being inserted but the pain disipates rapidly and I don't really feel the needle during the rest of the donation). Midway though another nurse came to ask how i was and i told her that the needle felt wrong. instead of putting the needle properly, my donation was stopped mid way even though I had said that i was fine and they told me that they would not be able to donate my blood to a patient because the donation was incomplete.

Second donation i told them i had issues before but they still messed it up. it was fine at first but became painful quicky (i did not say anything this time as i did not want my blood to be wasted again) and when i came home i noticed i had a bad bruise on my arm.

Third donation, the nurse struggled to get the needle in and moved the needle in my arm a lot. my vein was quite painful as a result for a while. i also had a small bruise from the needle insertion but the bruise did not get bigger during the donation so i did not mention it. most of the donation was painful because of that initial needle insertion but eventually, the pain wore off a bit and I realised that the pain was really just from the insertion. The staff had put my seat in a very reclined position (i was effectively lying flat) which was very uncomfortable for my arm (i could feel the needle press on my vein), led to poor flow so the machine kept beeping despite my best efforts and my back was starting to feel painful from the immobile and reclined position. I felt really stuck in that chair it was oppressive and scary. i could not un-recline my chair on my own and there was no available staff around so i sat a bit more straight in the chair on my own (despite the chair still being reclined) but staff saw me and told me i was not allowed to sit, that it was dangerous (i have donated many times in sitting positon and was always fine, i also never fainted in my life neither from blood donation nor anything else), that i would get a bruise... then they looked at my arm and saw the bruise and kept saying that it was because i had sat on my own when in fact the bruise had been there from the start of the donation and their colleague (who caused the bruise) had not seemed to care at all about it. now they were saying that they had to stop the donation because of the bruise and making a whole fuss about how it is only allowed to donate in reclined position for safety (i am pretty sure that i would have had less of a bruise if i had been seated properly), i was worried that they would waste my blood again and that i had endured pain from the first nurse and most of the donation for nothing! thankfully there was enough blood by then to use it normally and a new nurse came in to take the needle off and so on then paid extra attention to the (very small) bruise and got another colleague to check it too. they said that they had written a note in my file so that I could sit up next time if I wanted to and gave me a leaflet about what to do if the bruise gets worse.

I do not understand how so many blood donation nurses can be so bad with needles!!

I have donated many times and i know that my veins can be a bit small or hard to find but I did not have THAT MANY nurses mess it up every time when I was donating abroad, and if they did mess it up they always made sure the needle was properly put in the end, apologised, asked other nurses to do it if they struggled... here it is like they sometimes really don't know what they are doing and I can't tell them anything because when I try they don't understand or they hide behind one size fit all policies that I feel do more harm than good. A deep lack of critical thinking in my opinion.
