Got sore throat due to change in weather 4 days back. no fever, no running nose. sore throat improves but from last 2 days having little blood in spit?

SoarThroat aResponse: to a combination of issues; weather unlikely a significant issue, more likely a diversion of attention from more powerful internal issues controlling throat cells, tissues, muscles, immune system, etc.; all controlled from mind/brain. Blood in saliva is c/w enough tissue irritation/damage sufficient to break some capillaries, thus bleeding. Fragile throat tissues bleed from repeated coughing, etc.
