I had an episode of anaphylaxis , thought to be caused by a new medicine. Was taken off of it. Two months later had a similar episode but milder. Sudden diarrhea, faintness, itching of hands, body covered in red splotches, shaking. Normal, or slightly elevated B/P. Again last night, experienced same thing. Mostly passed in about an hour. No needed epipen, no breathing problems. Basic blood work is normal.
