I Was Tired For A Few Days Last Week..went To

I was tired for a few days last week..went to bed one evening and woke up with a terribly dry throat. I felt like I was choking.I drank water and then 2 large glasses of water with lemon juice. Though I was feeling more hydrated.. I discovered my uvula was swollen..red with white patchy spots.. and dragging on my tongue. Later that day... the an urgent care clinic diagnosed me with uvulitis..and put me on azithromycin. During the first few days I felt better; my throat pain was going and my Uvula was decreasing slowly. It's better today....some red spots on my throat still. My legs have been aching terribly for the past two days....my hips...and feet too. The quick strep didn't show strep and though they told me they sent out the culture..I just learned they didn't. I am extremely tired....lightheaded..foggy and not myself. I had a little bit of pain in my glands in my neck and I started to get a cold sore..but that came and went. I'm wondering if I could have mono.
