I have been in Argentina (Buenos Aires) for the past four months and recently, I've started to worry that I have contracted dengue. I visited Iguazú recently and I THINK all these symptoms began around that time.
My throat is incredibly sore -- my tongue feels almost swollen. I have muscle aches in my legs. And I have been having stomach pains, dull small pains that culminated in a very severe stomachache earlier this week. Also, one of the symptoms I read was "bleeding of the gums" and maybe I'm just a hypochondriac looking for symptoms, but I do have a cut on my gum.
I do not have a fever though nor a headache of any kind.
