• Trump’s doctor explains cause of red rash on his neck
• Redness comes from preventive cream and may last several weeks

The personal physician of U.S. President Donald Trump confirmed that the recent red rash on the right side of his neck is due to a topical cream used as a preventive skin treatment.

Dr. Sean Barbabella explained in a statement that the president has been using the cream for a week and that the redness may persist for several weeks before fading.

The doctor did not specify why Trump needed this treatment, and the White House did not immediately comment on the nature of the condition.

The rash was clearly visible during Trump’s appearance at a Medal of Honor ceremony, rising above the collar of his shirt and extending just below his ear.

At 79, Trump is the oldest president to take the U.S. oath of office.

Recently, repeated bruises on the backs of his hands sparked questions about his health. He attributed them to frequent handshakes and taking a daily aspirin dose higher than recommended, which makes him more prone to bruising.

Last year, Trump underwent two medical exams, including one involving cardiovascular imaging, according to his doctor, who confirmed in December that the president “remains in excellent overall health.”
