Be seen today
Arrange a prompt medical appointment if you develop a sudden crop of unexplained yellow, pink, or red bumps, particularly on the buttocks, thighs, knees, or elbows.
Blood tests are needed to check whether triglycerides are very high.
Seek prompt advice if you already have high triglycerides and notice new bumps, worsening diabetes symptoms, or lesions returning after they cleared.
Do not wait for a routine appointment.
Every sign above is quoted from the sofidex article on Eruptive xanthomatosis. If you are not sure, err upward — it is always reasonable to be checked.
