Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that you have an upper respiratory tract infection also known as common cold and the symptoms of sore throat,nasal and chest congestion seems to be due to it.. Blood from nose seems to be due to trauma to the small blood vessels in the nostrils due to vigorous and repeated snuffing as well as it can be due to inflammation in nostrils secondary to infection.. I would suggest you to take anti allergics like Levocetrizine., decongestnats like Phenylephrine, mucolytics like Ambroxol and anti inflammatory painkiller like Ibuprofen.. You can do steam inhalations and use a humidifier in your room.. You can also use decongestant nasal sprays and do saline nasal irrigations.. Do warm compresses over chest.. You should avoid spicy and chilled foods and drink plenty of warm water.. In case if still there is no improvement in a week consult an Otolaryngolgost and get evaluated and a thorough clinical evaluation and investigations like throat swab culture, blood tests and chest x ray can help in ruling out the cause and treat accordingly.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
