Sudden hand swelling and itching can be related to accidental injuries, such as compression injuries or sprains. Additionally, it may also be associated with insect bites, which can lead to symptoms like swelling and itching. If an individual has an allergic constitution, certain foods or pollen may also trigger hand swelling and itching. Another possibility is fungal infection, which can also cause similar symptoms.
