got injured at blood donation

am quite irritated now. wanted to do a good deed, but now the competition season (which i have trained so hard for) might be compromised.

the red cross came to NUS last friday for a blood donation drive. i decided to join the gang of people heading down to donate blood. i havent donated blood before and naturally felt a little apprehensive. but the fact that i'm doing a good deed (potentially saving the life of a stranger) put all my worries to rest.

too bad the nurse screwed up. i have several grouses all aimed at her incompetence. firstly, she told me that my vein is too small and that i need to exercise more. i told her that i exercised quite a lot (if hanging 50kg weights off myself to do pull ups is not considered exercise i dont know what is), but she just waved me off. seriously, since when did small vein equate a lack of exercise? secondly, my blood flow was rather slow. so for reasons known only to her, she repeatedly removed and inserted the thick needle into my vein to 'try to speed up the process'. the vein eventually got punctured and collapsed. the area around the injured vein is severely bruised. as a result my left arm is really weak now. thirdly, they gave me a anti-bruising ointment which i realised i was allergic to after application. i developed rashes around the area where the ointment was applied.

as of now, the entire area is bluish blackish, and the surrounding veins are reddish (prolly from the extra workload). it is painful when i press down on it.

i cant carry heavy things, i cant climb, and the competition season is just 2 weeks away.
