Hi.. Can understand your concern.. As per your complain you have symptoms of COMMON COLD which is a viral infection and includes coughing , sneezing , post nasal drip,chest and nasal congestion.. The moans or groans which you are worried occurs in case of congestion when you try to clear your nose and throat to breathe well. You need not to worry as when the cough will clear up the sounds will slowly disappear.. In case you have severe congestions you should take de cogestants containing pseudoephadrine like Sinarest ofr relief from congestion.. Taking nasal sprays for decongestion containing Xylometazoline like Otrivin can be helpful.. Inhaling steam with few drops of eucalyptus oil in it can help in clearing congestion.. Sucking Vitamin C candies can be helpful.. Drink plenty of water to maintain hydration as in case of cough and cold dryness of mouth and throat can induce coughing.. Hope your query is solved..
