What causes blood in puke along with weeks of fever, cough, and cold?

Hello,

Welcome to icliniq.com.

Based on the given information, I would suggest getting a complete blood test since the fever is lasting for more than three days despite taking Paracetamol. The blood stains and clots in your vomit are due to constant bad cough, and it is premature to be alarmed about it. To provide a complete diagnosis, I need a detailed history of your fever, such as the onset and timing of the fever. Whether you get it in the evenings or the daytime, high or low grade, do you have abdominal pain or joint pain along with your fever? For the cold, since it has been there for two days, I would suggest you take the following tablets and precautions. Vitamin C 500 mg twice daily after eating for 15 days, Amoxicillin 500 mg twice a day after food for five days, avoid cold water, continue Paracetamol 500 mg tablet for four hours once after food till you take a blood test and have only home-cooked food. I hope I have cleared your doubts. Thank you.
