A few years ago I had Mononucleosis. Since I thought it was a bad case of flu, it went untreated. But for several months, I had flu-like symptoms (fever, very runny nose and lot of mucus) every 4 weeks. After that I was left with a permanently sore throat.
When I finally went to a doctor he told me the mucosa in my throat wasn't healing, he did some tests and gave me medicines.
I ended up discovering that I had had Mononucleosis but at the time of the exams I was already healed (I tested positive to antibodies but had no more symptoms, except for in my throat.)
It's been a few years since what I have described, and now my throat is healed. However, I noticed that whenever I get the flu or a cold, I feel worse than I used to feel before that case of Mononucleosis (not just on my throat though).
Is it possible that having contracted Mononucleosis is the cause of my worsened symptoms with colds of flu?
