Actually no, the little staples in a&e do not need anaesthetic. I guess its hard if there are a lot to do but I have never seen this done before with anaesthetic. Its quick and the nurses staple themselves occaisionally to show its not unbearable. the whole staple gun is kept in individual sterile packaging so it is clean.
Also the steristrips is sometimes put over just to cover the stitches or staples. Some people dont like seeing them and I know that some SHers will unpick them so the steri's are there to avoid that in some cases.
I dont disbelieve that you may have been treated badly. I know how some staff can be but this is not on its own evidence of discriminatory behaviour.
you should report anything that made you feel you were not being treated fairly though. that is discrimination. Even if nothing comes back to you it can lead to better education of staff or just staff being careful so they dont get reported on.
I'm sorry they were mean to you. Some people in care shouldnt be there. I have always treated SHers kindly d respectfully, as I would anyone else who was vunerable.
Dont know if that helps.
