I have the flu and all and was sent to the ER Monday night by my doctor for iv fluids due dehydration due to severe throwing up from the flu, I go there and they put an iv in me to get lab work and they left the iv in me and I was there for about 3 hours. I'm using crutches for an injury so when I walked with them back to waiting room or to my ER room it hurt more because of using the crutches, I had them put the iv in right arm as the left one is hard to stick and usually bruises easy because of that. So I'm right handed so was using that hand to play my kindle while I waited and all so my arm was lil sore while having the iv in, long story short they never did give any fluids so I was left with an iv in for 3 hours for nothing, fast forward till Thursday night at bedtime I noticed a bruise on my arm where the iv was and from the pic you can tell it is a big bruise, I left it go and went to bed then yesterday I woke up and noticed my arm was hurting good bit in that sport where the iv was, I went to an appointment so was on my feet with the crutches a lot of the afternoon same as Wednesday and Thursday. So I came home and arm was really sore and hurt more to straighten arm out so I iced it. A friend told me that I should not be bruised and hurting like that and that I should go see my doctor about it and see what he has to say about the bruise as it is not normal for it to be like that I said I'm on steroids for my bad chest but did not start that till Tuesday.
Added (1). so I said maybe starting the pred a day after getting the iv made the bruise a lot worse and way to sore but I'm not sure and I said wedneday I went food shopping as I had no food here that I could while being sick and then was doing that and using crutches all day and same as Thursday so maybe that caused my pain but I'm not sure. The pain is not to bad right now when I stretch my arm out but it is still sore, should I go see my doctor about it or let it go?
Added (2). my friend is just worried that the bruise might become infected because of the size of the bruise and because of how much pain I'm in because of it, keep in mind that I'm already in antibiotic for chest infection
