All symptoms disappeared almost immediately (completely within 2 days). I took
Singulair again two weeks later (May 5) and exactly three days later, I was
at the hospital for the same symptoms only worse. My temp was not 102 like last time, but up to 106. I also had an odd, scaly, ring shaped rash on my torso and a blistering rash on my lower legs. My leukocyte count was 26, but all other blood tests came back within normal parameters.
