There are many causes for red dots and spots on the skin.

If you have health anxiety, multiple sclerosis may be the first thing that comes to your mind as to the possible cause of newly-noticed red dots on your skin.

“Virtually all symptoms of MS are a result of the damage MS does to the brain and spinal cord,” says Hadley King, MD, a board certified dermatologist who specializes in medical and cosmetic dermatology.

“That includes symptoms that involve the skin such as numbness, tingling, pain and itching, as well as phantom sensations,” continues Dr. King.

“There is some evidence that blood vessel fragility may be an aspect of MS. This has been noted on the limbs of MS patients, manifesting as blood spots called petechiae” [pronounced pee-tek-ee-ay].

“Petechiae can be seen in other autoimmune conditions as well, including scleroderma, rheumatoid arthritis and vasculitis.”

If you fear that you have multiple sclerosis, a neurologist can make the diagnosis after conducting tests.

MS is an uncommon cause of red spots on the skin, being that there are nearly 20 possible causes – including cancer. Here is more information.

Dr. King worked as an attending physician at Memorial Sloan-Kettering Cancer Center, specializing in cutaneous oncology. Her research has been published in numerous medical journals, and she’s been featured on “Good Morning America.”
