Question

Dear doctor, my baby, who hasn’t even reached a month old, has black and blue nails on their fingers. What could be the cause? Thank you.

Answer

Blue nails on the fingers are often due to weakness in Qi and blood, Qi stagnation and blood stasis, or coldness within the body. 1. If you are taking medication that is too cool and it injures the Yang Qi or obstructs its generation, stopping the medication will gradually lead to recovery. If you have experienced chest tightness, shortness of breath, palpitations, or fear of coldness in the past, although there may not be organic changes, it is best to have a related heart examination. In daily life, it is recommended to pay more attention to rest and drink more water.
