Why Do I Feel Itchy All Over After Being Bitten by Mosquitoes?

Some people experience generalized itching after being bitten by mosquitoes, commonly due to factors such as physical constitution, toxin stimulation, mental stress, insect bite dermatitis, or allergies. It is essential to seek medical attention promptly and address the underlying cause. Here are the main factors:

1. Physical Constitution

Some individuals have a sensitive constitution and react strongly to mosquito bites, resulting in generalized itching. Proper precautions should be taken to avoid mosquito bites.

2. Toxin Stimulation

Mosquitoes inject toxins into the skin upon biting, which can spread throughout the body via blood circulation, causing itching throughout the body. In most cases, this will subside naturally within a few days. If not severe, observation may be sufficient.

3. Mental Stress

Mental stress after a mosquito bite can heighten the sensitivity of skin nerves, leading to generalized itching. Relaxation and avoiding excessive anxiety are recommended.

4. Insect Bite Dermatitis

Large mosquito bites can cause insect bite dermatitis, manifesting as itching, swelling, and other symptoms. Medications such as paeonol ointment, calamine lotion, or clindamycin phosphate gel can be prescribed by a doctor.

5. Allergies

Individuals with an allergic constitution may experience pronounced reactions to mosquito bites. Antihistamines like cetirizine hydrochloride tablets, loratadine hydrochloride tablets, or chlorpheniramine maleate tablets can be prescribed by a doctor. Additionally, symptoms could also be indicative of systemic lupus erythematosus, necessitating prompt medical attention and treatment.
