Based on the appearance of the toe, I don't believe it's an ingrown toenail. What can I do?

Based on the appearance of the toe, it is unlikely to be an ingrown toenail. If it is an inflammatory skin reaction, it may be more common in winter and could be caused by cold exposure. It is recommended to always wear socks, have warm socks, and control the moisture in your feet. Using hydrocortisone and taking over-the-counter pain relievers like ibuprofen can help reduce inflammation. If the issue persists or the pain returns, it is best to consult a healthcare professional to rule out any infection.
