Woman Hospitalized by Sun: A Rare 'Vampire' Allergy

Emily Richardson, 36, has a rare and severe allergy to sunlight that triggers Stevens-Johnson Syndrome (SJS), a condition causing painful skin blisters and shedding. This 'vampire' allergy, which has caused her immense suffering, was misdiagnosed for years, with doctors initially attributing her symptoms to herpes.

Her first reaction occurred at one year old, and subsequent episodes at ages 13 and 27 were similarly misdiagnosed. Since contracting COVID in 2021, Richardson has been hospitalized four times due to SJS. She believes her immune system has been significantly compromised by these recurrent reactions.

To avoid hospitalization, Richardson must meticulously protect herself from UV exposure, wearing full coverage clothing even for brief outdoor excursions. She is now using TikTok to educate others about SJS and her ongoing fight for medical recognition and support.
