Hi, may I answer your health queries right now ?  Please type your query here...  hi my name is emmaly and I was wondering about my niece and that she has a runny nose sinus congestion green snot and a cough and I dont know what to do. She is so congested that it sounds like she is having trouble breathing. Could u help cause from the look of it, its looks like a sinus infection and allergies togther
Hi, I understand your query. Sinus infection is due to blockage of sinus outlet by allergic inflammation/ thick mucus plug... collected secretions in sinuses get infected to form sinusitis.  The origin of all the symptoms being similar (allergy,-congestion- infection)& there being anatomical connection between Throat-nose- sinus, common cold, sinusitis, throat & lung involvements tend to follow each other/ seen all together.  The breathing trouble can be due to congestion & blocked nostrils Or allergic bronchitis A sufficient course of suitable antibiotic/ anti-inflammatory & anti-allergic Chat Doctor.  Thanks.
