I've been itchy a lot of the time on it on upper back, chest and upper arms. The itching wore off about
3 weeks after #3 . Had #4 today and feel the odd itch. It hasn't ever broken out to a rash yet. Having always had sensitive skin anyway I'm used to a pretty strict regime of not scratching, non-perfumed washing powder and washing only with tiny amounts of soap. I have put a basic aloe vera gel on it sometimes. So far so good.
I have no idea what the itching is caused by but I have seen others report it, trying not to worry about
it. I saw that the mixture contains histidine so I don't know if this is a factor. Today though I also got wondering as I noticed my MPV in blood count has raised and I came across research that this is linked to urticaria
