What was the result of your "patch test" ?
In 4/2014 I had red swollen lips & a bit of red around the mouth. Tried all the ointments, creams, antibiotics, prednisone, cortisone, viral, etc. Nothing helped; it just finally faded away.
1/2015, the same red lips reoccurred with a larger red surrounding the mouth, which began extending up to the nose & down to the chin. Then, a 1-1/2" red stripe appeared on the front of my neck and blotchy chest.
