Urticaria may worsen or recur during menstruation, which is related to hormonal fluctuations. Women are advised to pay extra attention to daily care during this time and record any changes in symptoms for medical advice.

The specific manifestations usually fall into two categories:

1. Worsening of premenstrual symptoms: Some women may experience increased skin sensitivity before menstruation due to a drop in estrogen levels. Existing urticaria symptoms may become more pronounced, and itching may intensify.
2. New skin rash during menstruation: A small number of people may experience mild wheals or erythema for the first time during menstruation. This is usually related to temporary changes in immunity, and these symptoms usually subside gradually after menstruation ends.
If you encounter this situation, you can try the following methods:
First, wear loose cotton clothing to avoid rubbing your skin; the bath water temperature should not be too high to reduce skin irritation.
Secondly, getting enough rest and appropriately reducing strenuous exercise during menstruation can help stabilize the body's condition.
Finally, if the rash spreads or the itching severely affects your daily life, you should consult a doctor promptly and avoid using medication for an extended period without medical advice.
Recording the time of each symptom onset, along with dietary and lifestyle details, can help doctors better determine the cause. Maintaining a relaxed mood and avoiding anxiety can also help alleviate discomfort.
