I had the EXACT same symptoms this weekend, it must be some bug going around, once I blew that same **** outta my nose, almost immediately my throat wasn't dry or burning nearly as much anymore and I'm almost feeling 100% better now, hope you had the same results because the other day was just miserable for me as well
Nose bleeds are common, especially when the nasal membranes are inflamed, as they are with infection. Most virus infections resolve in a week or so, the flu somewhat longer. If you continue to raise blood from your nose or throat, after the cold/flu symptoms have resolved, you should see a doctor to be examined.
