What causes severe blocked nose and little foamy saliva from mouth?
Patient: My Four year old son had cold on monday. When he was sleeping facing his face up, His nose was heavily blocked and very little foamy salvia came out his mouth. Is it cause of concern? Doctor: Hi,Does he have fever? Was the frothing associated with any jerking or stiffening of body?  If not, we need not worry. Nasal stuffiness and block suggests rhinitis as a part of flu, common cold. A blocked nose can interfere with normal frequent swallowing of saliva to clear mouth, resulting in drooling. Just apply some nasal decongestants. I usually gives oxymetazoline nasal drops (2 drops on both sides, 3 times a day) for 5 days.Take care. Hope I have answered your question. Let me know if I can assist you further.  Regards, Dr. Muhammed Aslam T. K., Pediatrician
