stress related maybe... I get terrible bouts of itching arms and back mostly the thing I find helps most is cooling the areas with a cool face cloth or if its really bad a tepid bath
Is it there all the time,and when you scratch doe's it itch even more to the point of wanting to take the skin off(harsh I know).This happened to me and found out it was the shampoo I was using in the shower.I was told sometimes when you get older your skin changes(becomes more sensitive)to things it would not normally.On monday I was scratching my legs off all day I was demented,stripped down and washed them to notice they were blue off a new pair of jeans after washing legs itch disappeared.thought this might help you.
Ive had this before, I actually itched so much that I scratched till I bled. nobody had a clue what it was, and you couldnt actually see anything. I just persevered with anti histamines etc and it eventually went. Not much help im afraid, but I sympathise.
Laelia - hahaha no new bed sheet....
Fredkins - have thought about shower gels. Have not had any new ones.
Tambo - No leather furniture.
Smowball - my neighbour suggested anti histamines as she had something similar recently.
Rowan - I only take paracetamol.
I hadn't changed my shampoo either same one i'd always used,but for some reason i was having an allergic reaction to it (just body change).Hope you get sorted out.
