Mild bleeding, wounds in nostrils.

Hello. About 2 weeks ago i got severe cold maybe because of some dust or something because I was sneezing continuously and aggressively. I took sinarest tablet and the mucus started hardening in my nose. Soon the hardening became irritating so i was plucking them out but it started bleeding enough to stain my handkerchief. The hardened substance in my nose kept coming back and whenever i would sneeze, a little bit blood would come. Now the bleeding has become a bit less but it hurts because the booger or hardened substance is painful in my nostril. This was happening only in my right nostril but now the hardening started in my left as well. I don't know if I'm explaining this well.. but kindly let me know if i should do something..
