i just got over mono about a month ago and felt so much better. but now im sick again.  I have a sore throat, headache, loss of appetite, nausea, and really swollen/puffy eyes.  I had these same symptoms when i had mono.  Could it have come back?  and what could cause my puffy eyes?  I want to get rid of them because its kind of embarrassing to go to school.  Im also 14
Hello, It can take mono a long time to completely go away, even up to 6 months. However, your symptoms may be due to allergies, so you could ask your doctor about taking a non-sedating antihistamine. Using cool compresses (not ice) on your eyes may be helpfulRegards
