Neck rash caused by ‘preventative skin treatment,’ Trump doc says

President Trump’s doctor downplayed a red rash on the commander-in-chief’s neck as the byproduct of a “preventative skin treatment.”

The 79-year-old president raised further questions about his health Monday when he appeared at a Medal of Freedom event at the White House with a dark-red rash on the right side of his neck, blooming out from under his collar.

“President Trump is using a very common cream on the right side of his neck, which is a preventative skin treatment, prescribed by the White House Doctor,” White House Doctor Dr. Sean Barbabella said in a statement.

“The President is using this treatment for one week, and the redness is expected to last for a few weeks.”

The statement did not include what skin condition requiring a prescription is afflicting Trump, but causes could include eczema, an allergic reaction caused by food or medication, shingles and others. The statement also doesn’t clarify whether the rash was caused by the prescription medication.

Trump has previously drawn scrutiny for falling asleep during meetings, appearing with bruised hands often covered in makeup, revelations of unspecified medical imaging and a diagnosis of chronic venous insufficiency, which can cause swelling in the legs and ankles.
