My fish tank is very small, so I sprinkled the amount of salt for cooking. I have raised it for a year. I am very distressed. Urgent!

Kindly note: The reply is only for your reference and cannot replace clinical diagnosis. Please go to the relevant hospital for final diagnosis:

Your boyfriend is suffering from cholinergic urticaria.

It is recommended to go to the dermatology department for diagnosis and treatment! If you treat yourself, you can take some anti-allergic drugs, such as 1 tablet of cetirizine/day + 1 tablet of ranitidine/2/day + 2 tablets of Vc tablets 2/day.

Cholinergic urticaria is a type of hives that people often call urticaria. When the body temperature rises slightly due to heat, mental stress, hot food or drink, or after exercise, the increased blood flow stimulates the temperature regulation center in the brain, excites the cholinergic nerves and releases acetylcholine. It is because the body is allergic to the chemical acetylcholine that we call the symptoms caused by allergies cholinergic urticaria.

Symptoms of cholinergic urticaria

① No rash will appear, but there will be obvious tingling and severe itching sensation.

② Mostly occurs in adolescence, usually after exposure to heat (hot drinks, hot baths), emotional excitement, and exercise. Symptoms subside when you stop exercising or calm down. In severe cases, it may take months or years for the symptoms to completely subside.

③ Red wheals of about 2 mm in size often appear on the skin of the trunk and proximal limbs (except the axilla, palms and soles). These wheals come and go quickly without leaving any trace. In severe cases, there may be gastrointestinal symptoms such as abdominal pain and diarrhea.

It often occurs in adolescence, after exposure to heat (hot drinks, hot baths), emotional excitement, and exercise.
