I have been having severe cold from 1 week, starting few days I had my left nostril blocked completely, I was breathing through only right, however from past 2 days my right nostril is also getting clogged up. When ever I keep blowing out my nose the next 10mins itself my nose gets stuffed again. I have mild headache exactly above my eyebrows. Night times it's even difficult, few times I breathe only through mouth. I have been doing steam inhalation, drìnking hot water,salt water gargle and I take hot shower but no use till now.
