Ok - I'm 25/m and have been having some weird symptoms for a few months. I'll try to run it down and see if any of it makes sense.
In January I came down with a severely swollen left tonsil covered in pus, bad fever for a few days with a sore painful lymph node on the left side. Antibiotics were prescribed twice but did not help. It took about three weeks to gradually go away.
Everything was fine for a couple months and then I developed a bit of a cough that got pretty bad by about the beginning of April. It's calmed down a little but has never quite gone away. It goes back and forth between being productive and nonproductive.
Also for the last month to six weeks, I've gotten chronic canker sores -- about one a week. Plus, about three weeks ago, I developed oral hairy leukoplakia on my tongue. I read online that this can be a sign of HIV, but I got tested and it was negative.
Two weeks ago, I noticed my submandibular gland has been enlarged on the right side. It feels rubbery but not painful. It definitely did not pop up out of nowhere like it did when I had the original tonsil problem. Part of me thinks it's always been there but all the other symptoms made me really notice it. So I went to the doctor. He gave me two more courses of antibiotics which have not worked and an antifungal which took care of the oral hairy leukoplakia.
When the antiobiotics did't work, he sent me for a ton of blood tests. Had about five vials taken. And the test came back positive for mono.
Here's the part where I don't understand... the fatigue, which is the main symptom, has only set in in the last couple days AFTER I've been diagnosed.
So the main question I have is this... when exactly in the course of all these symptoms do you think the mono actually started?
The reason I ask is because I read online that sometimes a false positive mono test can be caused by something much more serious like lymphoma or leukemia. And since the symptoms have been so inconsistent and drawn out, I'm wondering if maybe that's the case.
If this has been mono all along, why would it take months for the fatigue to set in? That's what scares me about this possibly being something more serious.
I know this is long and confusing, but I'm hoping anyone who knows this stuff better than me can help. Thanks!
