I'm sorry to hear about the pain, swelling, and redness in your toe. These symptoms could indicate an infection or an inflammatory condition such as gout, especially since the area has become reddish after using ice and hot water therapy.

Here are some important steps you should take:

• Avoid further self-treatment with ice and hot water as alternating temperatures might worsen inflammation or cause skin irritation.
• Keep the affected toe elevated to reduce swelling.
• Avoid putting pressure or weight on the toe to prevent further injury.
• Since the redness and swelling have persisted for a week and worsened, it is important to consult a specialist doctor promptly, preferably a rheumatologist or an orthopedic doctor, to evaluate the cause and provide appropriate treatment.
• If you experience increasing pain, spreading redness, fever, or any signs of infection, seek urgent medical care immediately.

Based on the information about medications like Ubexa (febuxostat), which is used for gout management, if you have a history of gout or have been prescribed such medication, it is crucial to continue under medical supervision and not stop any prescribed treatment without consulting your doctor.

Please see a doctor soon for a thorough examination and appropriate treatment.
