I'm sorry to hear about your broken toenail and the pain you're experiencing. Here are some steps you can take to care for it:

• Clean the area gently with warm water and mild soap to prevent infection.
• Avoid putting pressure on the injured toe and keep it elevated if possible to reduce swelling.
• Apply an antiseptic ointment and cover the toe with a sterile bandage to protect it.
• Take over-the-counter pain relievers like paracetamol or ibuprofen to help manage pain and inflammation.
• Watch for signs of infection such as increased redness, swelling, warmth, pus, or worsening pain.

If the pain is severe, the nail is deeply damaged, or you notice signs of infection, it is important to see a podiatrist or a dermatologist promptly. They can assess whether you need further treatment, such as antibiotics or nail removal.

Please avoid self-medicating with antibiotics like Moxclav (Amoxycillin and Clavulanic acid) without a doctor's prescription, as inappropriate use can lead to resistance and other complications.

If you experience severe pain, spreading redness, fever, or any other concerning symptoms, seek immediate medical attention or contact emergency services.
