Hello, I am 44 years old with a chronic sinus infection, I have extreme coughing bouts in the mornings from drainage. when I am coughing my head is in excrusiating pain and my sinuss as well. this morning, after the bout I had to blow my nose and was blood twice, the second with a small blood clot. Is that normal. Also, can you cough yourself into brain damage.  cant wait to hear from you..Sharon
HelloWelcome to ChatDoctorI understand your concerns. As such coughing doesn't cause brain damage. Vigorous coughing and sneezing will lead to rupture of small capillaries in the nose that will cause bleeding through the nose. I would suggest you to take antibiotics for chronic sinusitis along with inhalation of the minaret vocals. This will help to open up the openings of the sinuses and brings down your symptoms. Hope I have answered your query. Thank you
