Hello, Welcome to HCM, From your complaints it looks like that you are having a acute sinus infection and this is causing the pain and nose block. You may need antibiotics for the infection and should meet your doctor for the prescription. For the time being you can take tablet paracetamol 500 mg two to three times a day for the pain. Also take steam inhalation 2 to 3 times a day and oxymetazoline drops two drops four times a day which will reduce the block. This is a short term solution and antibiotics will be required. So please meet your doctor. Thank you.
