Ijust got over a cold but now i have a sore throat and my nose is clogged up and my snot is green? what could it be? do i have another cold right after getting over one like 2 days ago? could it be strep throat?

You could have a sinus infection. Where  you on any antibiotics? Change your toothbrush when you get sick. ( It should actually be changed every 3 months) but if you have a cold and to prevent further illness, I would change that tooth brush. Do you have a fever? But try to call your Primary care Physician or go to your nearest Urgent care.  Hope you feel better, Drink lots of hot green tea with honey.
