Shanyna Isom, a law student in Memphis, suffered an asthma attack a few years ago. As a result, she was prescribed steroids, which had a terrible consequence for her. She immediately started itching all over her body. She began to grow scabs, especially on her legs, which quickly spread to the rest of her body. Although she is getting better now, after doctors ascertained that she had a Vitamin A, B, C, D and K vitamin deficiency, she is still struggling with deformities on her face. She looks now like she has had a bad sunburn but at the worst, she has had fingernails grow out of her skin instead of hair.
Her bones and vision were also affected, and she cannot get around now without a cane. She needs help even getting out of bed in the morning because she is so weak in the legs. Eventually, doctors in Baltimore at the legendary Johns Hopkins hospital there, realized that the black scabs covering her body were nails. She has to be careful not to get too close to others, or they will be pierced by the sharp nails. Nails grow where hair on her skin should be growing. Wherever there was hair, now there are nails, in other words.
The reason behind the affliction, at least generally, is that Ms. Isom’s skin cells grow at 12 times the normal rate. This suffocates her skin and causes the nails to grow in this unusual way.
