3. Flulike Symptoms Occur First
The first symptoms that are known to occur in most cases of SJS are the type of symptoms that will mirror the beginnings of your standard cold or flu infection; the only difference between the two is the fact that you will very soon notice that the flulike symptoms don’t go away in the expected time, and this should be the very first sign that something else is wrong with your health. You should see your doctor if this is the case, even if you experience only a longer-than-usual bout of the flu without the other symptoms of Steven-Johnsons Syndrome being present.
In most cases of SJS, these symptoms soon set over into the characteristic rash associated with the condition, and other severe symptoms (including organ failure) will set in if the condition remains untreated.
If you have taken flu medication that aggravates symptoms, see your doctor after discontinuing use.
