When I'm throwing up how come there is like brown specs or brown spots coming up along with clear mucus, I am having stomache pains, but I am on medication called azithromycin because on tonsillitis, then when I try to sleep then wake up I have a hard time breathing when I wake up and have to use an inhaler I am also coughing too, so could you tell me what it might be or what to do? Thx
