There was a thread for this topic, but I think it has been moved or closed. Every summer, I have severe itching on my forearms. A guy who was a surfer posted a remedy. He found that applying a high SPF sun screen to his arms stopped the itching. It really works for me!!!!! Try it!
I have been reading about all the itching under the skin posts. I have just recently aquired this horrible random itch on both forearms from wrist to elbow. It is a small area on the top only. The right arm much worst than the left. I thought it was some kind of poison ivy or allergic reaction. The itch when scratched will leave raised welts. I seem to have gotten this shortly after a day weeding around my property on the first hot sunny day after spring. I was not wearing sunscreen. I thought at first I had gotten sun poisoning because I had gotten this measle type rash that itched something awful. I told my daughter about this (she is an EMT). She said a friend of hers had something similar and the doctor told her friend to wash her body with a strong dandruff shampoo. He told her it was a type of fungus living under the skin that may have gotten there while her pores were open during a hot day of sun and sweating and some outdoor activity she did had the fungus on it. She followed the doctors orders and repeated bathing and using the dandruff shampoo as a bath wash. It worked and she is free of this itch.
I used this method on my arms and it is almost completely gone from my left arm. My right arm, which has it the worst still needs some additional applications. My daughter thinks it's the Zinc in the dandruff shampoo that is helping the situation. My skin on my right arm feels almost like that of an elephants hide from all the scratching. I can also feel little lumps and bumps under the skin when I run my hand over the area. LOTS of skin moisturizer is needed until my skin makes a slow comeback and repair.
