Itching experienced in spring and fall

When spring and fall changeover periods come, my whole body itches so much that I scratch until I bleed. It's an unbearable itch that can't be relieved by anything else.

However, there are no particular skin conditions such as psoriasis or other diseases. During spring and fall, I scratch my entire body for about a week due to itching, causing wounds from scratching. Then, the skin heals and becomes normal again.

During this time, I cannot even go to the bathhouse. It looks like a victim of domestic violence.

I get scolded even at home. When I scratch myself, everyone tells me not to come near.

I also dislike my condition, but I can't help it. I wonder if it's due to pollen, so I don't go out much in spring. In autumn, I think it's because of dryness, so I pay attention to skin moisturizing. Still, my illness doesn't improve. I'm worried.
