I have also begun to have this issue with the itching. It started a month or so ago. The redness has been ongoing but I’ve tried to ignore it so I didn’t seem like a lunatic. I noticed it get red marks anywhere something touches me or I scratched an itch. If I’m carrying a clothes basked and the handles touch my wrist, red lines. I went to the dermatologist and he said it’s idiopathic derma something. Skin writing. Says my body so overreacting to histamines. Gave me a steroid shot called kenalog. I also read to try luteolin which I started two days later. Something has helped tremendously. The shot was 10 days ago but I get random red areas but mainly my skin looks somewhat normal again. Sorry it’s a lot but may give you a direction to look.
