I fell down the stairs yesterday morning and banged and twisted my right arm. It swelled up one specific area and was very painful, it also came up in a bruise. I left it thinking it was just twisted/bruised, however the pain has gotten worse and what I thought was swelling now looks like a lump and feels hard. I have good movement in my wrist even though it is painful and I have full movement in my fingers. The bruise is not as dark and I would have thought considering how hard I hit it. It is my lower arm on the side with my little finger about an inch below my wrist joint. I hate wasting NHS time and was just wondering, would it be worth visiting A&E for an xray or should I just leave it ? Many thanks for your time !
