Is this sign of necrosis, infection, or skin graft rejection? Please help (Photo)

It's understandable to feel concerned about changes in your skin, especially after surgery. While I can't provide a definitive diagnosis without an examination, I can offer some general insights.

The symptoms you're describing, such as the sudden appearance of a red mark and tingling on your nose, could potentially be due to several factors. It is less likely for a skin graft to be rejected after two years, as graft rejection typically occurs soon after surgery. However, it is possible that there might be other issues such as:

Infection: Although you mentioned no pain or swelling, sometimes infections can present with minimal symptoms. It's important to monitor for any additional signs such as increased redness, warmth, or discharge.

Irritation or Trauma: The area could be irritated from external factors like skincare products, sun exposure, or minor trauma, which can cause redness and tingling.

Vascular Changes: Changes in blood flow or pressure in the area could also cause redness and tingling, although this is less common.

Nerve Sensitivity: Tingling might suggest some nerve involvement, potentially due to irritation or pressure on the nerves in that area.

Given your concerns, I recommend contacting your surgeon or a dermatologist for an in-person evaluation. They can provide a thorough examination and, if necessary, recommend appropriate tests or treatments. Early consultation can help address any issues promptly and ease your worries.
