Hello. I have been worried for quite some time over what has happened to my arm. There is a small cut on my arm which had healed up very well however, soon after it had healed this red, lumpy, itchy and burning mess (as I can describe it) appeared. I don't know how it could of appeared however, it hasn't got better since. It has been there for around 5 months now and sometimes when I do itch it, it bleeds. I'll add a photo so you know what I mean, ignore the semi colon - that was for mental health awareness.
Thanks to anyone who can help.
