What causes sudden fever accompanied by ankle pain, and what should be done about it?

Generally, sudden fever accompanied by ankle pain may be caused by conditions such as sprain, rheumatic arthritis, systemic lupus erythematosus, and others. Symptomatic treatment should be based on specific circumstances. Details are as follows:

1. Sprain

If the ankle is sprained, it typically causes ankle pain. In patients with poor physical health, fever may also occur simultaneously. It is recommended to apply cold compresses to the affected area. If the pain persists for a long time, the patient should go to the hospital to determine whether there is a fracture.

2. Rheumatic Arthritis

Rheumatic arthritis is a type of allergic reaction disease, characterized typically by migratory polyarthritis. It commonly symmetrically affects large joints such as knees, ankles, shoulders, wrists, elbows, and hips. The affected joints often show inflammatory signs such as redness, swelling, heat, and pain. The inflammation may also affect the immune system, leading to fever. Patients are advised to take medications such as enteric-coated aspirin tablets or ibuprofen sustained-release capsules as directed by a physician.

3. Systemic Lupus Erythematosus

Systemic lupus erythematosus is a systemic autoimmune disease associated with multiple factors including genetics, sex hormones, and infections. It can involve multiple systems and organs throughout the body and may present with the aforementioned symptoms. Patients are advised to take medications such as methylprednisolone tablets or prednisone acetate tablets as prescribed by their doctor.

In addition, other possible causes include diabetes, malaria, sepsis, bone cancer, etc. Patients are advised to seek timely medical attention when experiencing discomfort to avoid delays in treatment. Additionally, they should maintain a light diet and ensure adequate rest.
