The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced bright red skin bump. This list does not constitute medical advice.

  1. 1.Non - Specific Dermatitis (Skin Inflammation)

    Dermatitis is the inflammation ("-itis") of the skin ("derma" is a layer of the skin). It can be caused by any number of causes, from allergies to infections to autoimmune issues. Dermatitis of Normal Variation (also called, "NOS") means that all of those other causes of your rash have been ruled out. This is very common.
