Allergic reaction or Lupus?

I put on makeup one afternoon to go take pictures at the walmart. While applying the makeup, I used this new pencil eyeliner (I had used it once before). I accidentally put too much, so I grabbed a cotton ball and doused it with Palmer's Cocoa er Lotion to remove the eye makeup. I rubbed the cotton ball ALL over my eyes and cheeks. I finished putting on makeup, and I left the house. Later that day, I got into an argument with my husband and I cried a little bit. About an hour after I cried, I noticed my face turning really red and spotty, even all the way down to my chin, but mostly around my cheeks and under the eyes. I took a Benadryl because my husband said it looked like an allergic reaction. I got really tired from the Benadryl and went to sleep. I woke up in the morning, my face felt kind of funny - like I couldn't open my eyes all the way. I looked at my face in the mirror, and my eyes (above and below) and cheeks were swollen and puffy. I looked pretty scary. I immediately told my husband and we got in the car and drove to the doctors office. He said it looks like an allergic reaction, and he gave me Prednisone 6 day pack, and told me to take Claritin during the day and Benadryl at night. Well, the Claritin during the day and the Prednisone works great - but Benadryl barely works at night. Around bedtime, my face starts to get a little itchy and I see some redness and swelling. It is now day 3 of the 6 day Prednisone pack and my facial swelling has completely gone down, but around night time I'll begin to see a bit of redness. Sometimes on my left cheek under my eye, and sometimes on my right cheek under my eye. I am worried because I was reading online about Lupus and it presents itself in a rash on the face. I don't have any of the other symptoms of Lupus, but my question is, can Lupus make my face puffy and swollen? To me, I guess it sounds more like an allergic reaction, but my doctor said if the swelling doesn't go down by Monday, that I should come back in because it could be something "different." When he said "different" what does he mean?? Anyone have any ideas? I'm really scared.
