I have had a cough with chest pains then it went away and now I got dark yellow mucas and now small red bumps are starting to appear and itch really bad

Have you gone to a doctor? If not why not?

Bumps WHERE??
And what COUNTRY??

Yeah... go to the doctor. Tell them right away that you may have something contagious so that just in case you don't infect anyone else!

-How old are you?
-When did this start?
-Where on your body are the bumps?
-Do you have a fever?
-Does anything on you hurt/ache? Like your throat?
-Have you ever had chicken pox?
-Have you ever been vaccinated against chicken pox and measles?
-Could the bumps be due to an allergic reaction?

Please, go see a doctor though. We can only make educated guesses as to what it is. A live doctor can actually diagnose and treat you, so you get better!
