I'm confused by your post, as you say that came around a week later? And you still have a dea arem where you where jabbed??
I would assume that you spent this week in hopsital? As you would have to had to have a fluids via a drip to survive a comma caused by fit and/or hypo???
I've not experienced a glucogen to bring me aaround from a hypo, but my husband has on several occassions, and on one occasion the paramedic pushed glucose straight into the vien via a cannual the latter wasn't a pleasent to watch, as the paramedic actuall had to knee on his arm while carrying out hte procedure, and I had to help to basically pin him to the floor just incase, he started to come around while the paramedic was pushing the glucose into the vien, which isn't a easy thing to do...
Both these method use on him, has never required a hospital visit as he came round, and I can't remember him saying that he had any problems with soreness of the arm afterwards...
However if you were driped while in hospital, it could actually be the cannual for the drip that has caused your problem, I have had this on a couple occasions, where I've had to have a cannular inserted and used for a extended period of time, and it has reacted causing problems this was very sore indeed and lasted quite a while..
If concerned seek medical advise with you GP
