What are the causes of hives?

I also frequently had trouble sleeping due to the itching.

I was curious about the cause of hives.

I searched the internet,

I asked the people around me as well, but

It is difficult to find the exact answer.

Food allergies, with several possibilities

I heard that there are stress, environmental factors, etc.

But in my case, of all things...

I cannot tell what the cause of the hives is.

I just feel frustrated because it’s not there.

In the case of food allergies, especially recently

Even though I have never eaten new food

Symptoms I am confused because an image is appearing.

Stress is compounded by my busy daily life these days

It is quite a lot.

While environmental factors cannot be ruled out,

There hasn't been any particular change in the environment, so I don't know what the problem is.

If anyone has ever experienced hives,

Could you share your experiences?

What caused the hives,

And I am really curious about how it was treated and managed.

For example, if you have to avoid certain foods,

It would be very helpful if you could advise me on changing my lifestyle habits.

If anyone knows the cause of hives, please let me know.
