Urticaria is characterized by wheal, local flat uplift, different sizes, as small as broad beans, as big as palms, and can also be connected into one piece, such as maps and rings. Appear in batches, leaving no trace after fading. Just like you said, it's like a wind mass bitten by mosquitoes, sometimes it stings.
I've been there before, and I've had urticaria and sore mouth. Don't worry, the swelling in the mouth will subside over time and will return to its previous appearance.
In addition, the appearance of urticaria will lead to bright red, reddish or porcelain white air masses of different sizes on the skin, which may induce other diseases if not treated in time. So I suggest you go to the hospital for a check-up. I have had urticaria, and I can understand how you feel.
In the meantime, please don't eat fish, eggs, seafood, beef and other things. The reason why you can't eat it is because these foods are the most likely to induce urticaria. Please don't eat these things until you know the allergens.
I used to take a lot of medicine and see a lot of doctors, but it recurred as soon as I finished eating it. I can understand anxiety and painful fears.
So I suggest you go to the hospital to check the allergens, so that you can know what you can't eat, including other foods containing this kind of thing, in order to avoid the recurrence of urticaria.
Note: Some urticaria is sudden. If it is not treated in time, it will be more troublesome and cause other diseases. So, don't delay, go to the hospital for examination as soon as possible.
If you have any questions, please feel free to ask me. I hope you can get well soon.
