Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems like you are suffering from Chronic Maxillary Sinusitis
leading to congestion, blocked nose and discomfort breathing..
You can consult an Otolaryngologist and get evaluated and he can advise you to get investigations like PNS VIEW of sinuses or MRI done to rule out the exact cause of the symptoms and if Sinusitis is confirmed he can advise you to take antibiotics like Cephalexin
, anti inflammatory painkiller like Ibuprofen, decongestant Oral as well as Nasal like Phenylephrine
, steam inhalation, saline nasal irrigation
and do warm compresses over chest..
Use a humidifier in your room..
Hope this information helps..
Thanks and regards.
