I Was In Peru When This Happened, A Couple Of

I was in Peru when this happened, a couple of weeks ago. One day I had red flushed cheeks like if i had been out in the Sun ALL Day. My stomach down to my knees felt burning. I thought i had temperature, i had a bit of a chill. I took a panadol. I woke up in a sweat. Next Day i had diahrrea, watery, watery bowel movemnts for two days. I only had strong tea, soup, gatorade and yogurt. I started taking floratil. Then my gland behind my left ear was very swollen. The one on my groin also, my whole left side felt different, i took antiinflamatory for a couple of days. Then the swollen gland behind my ear reduced in size but smaller bumps appeared on my scalp and neck. Then a rash appearred on my armpits, under my bust and on my back.
It was not itchy but i didn't like the look of it. Salmón red oval shaped. I was told by a peruvians doctor i had a viral eruptive but i dont know the name. A blood test showed a mild infection. The hives like bumps on my neck, forehead and one side of my face. i flew back home TO Canada. My doctor here told me it was a virus. Its been 3 weeks now. I still have some of the rash although it is dark looking. I have Hashimotos hypothyroidism and take Synthroid every day for the last 3 years.
