Itchy back when leaning forward
For a few years now I've been getting a fairly intense itch in my upper back (around my shoulder blades) whenever I lean forward or bend over.
It begins within a few seconds of leaning forwards and becomes more intense the longer I'm in the position (eg. tying shoelaces, putting on socks, picking something off the floor... usual leaning forward type activities).
Sometimes it gets so uncomfortable I have to stand up and start scratching.
It tends to be worse in the morning just after I've showered.
There doesn't seem to be any external rash or actual skin problem and the itch actually feels slightly internal, as if it were just under the skin.
My guess is something to do with the flow of blood into my upper back when bending forward which... heats the skin there and makes it itch or something.
Maybe this combined with a mild allergy to my washing powder?.. (I've changed before to no avail)
By this logic I'd expect it to happen to everyone, or at least be fairly common, yet I can't score any hits on Google.
I've lived with it for years as I said and am happy to live with it for many more as it's no more than a mild discomfort. However, it would still be nice to understand the biology and by doing so possibly find a way to alleviate symptoms.
Thanks for your time,
