Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns.
As per your complain blood smell in nose while having sever cold and
sneezing is not a sign of something very serious as when there is
severe cold and excessive sneezing there can be inflammation inside the nose over the nasal mucosa as well as there can be slight bleeding due to trauma caused due to vigorous sneezing..
Nothing to worry as it will get resolved soon as the cold and congestion will subside..
You can start taking decongestants like Pseudoephadrine and nasal decongestants containing
Xylometazoline..
You can take anti allergics like Levocetrizine..
You can do steam inhalations and warm saline gargles..
You can take anti-inflammatory painkiller like
Motrin..
Avoid spicy and chilled foods..
Do saline nasal irrigations and take ample of warm fluids..
In case of no resolution in 4 to 5 days consult an Otolaryngologist and get evaluated..
Hope this information helps..
Thanks and regards.
