Potential causes of your symptoms:

- Allergic reaction: An allergic reaction can cause a sore throat, cold sweats, and hives (which can appear and disappear quickly). Common allergens include foods (such as peanuts, shellfish, and milk), insect bites, and medications.

- Viral infection: A viral infection, such as the flu or a cold, can also cause these symptoms. Viral infections are often accompanied by other symptoms, such as fever, cough, and congestion.

- Bacterial infection: A bacterial infection, such as strep throat, can also cause these symptoms. Bacterial infections are often accompanied by other symptoms, such as fever, swollen lymph nodes, and pus-filled sores.

- Anxiety: Anxiety can also cause physical symptoms, such as a sore throat, cold sweats, and skin rashes. Anxiety is often accompanied by other symptoms, such as feeling restless or on edge, difficulty sleeping, and muscle tension.

It's important to see a doctor for a proper diagnosis of the cause of your symptoms. The doctor may perform a physical exam, order blood tests or allergy tests, and ask you questions about your medical history.

Treatment for your symptoms will depend on the underlying cause. For example, if you have an allergic reaction, you may be prescribed antihistamines. If you have a viral infection, you may be advised to rest and drink plenty of fluids. If you have a bacterial infection, you may be prescribed antibiotics. If you have anxiety, you may be referred to a therapist for treatment.
