<s>[INST] Hello doctor, I got fever a few days back along with joint pains, headache, and a running nose. Still cold persists although it has been a week since I got rid of fever. To my notice, while sneezing I noticed blood (3 to 4 times out of nearly 20 to 25 times, I sneezed). [/INST] Hello. By the symptoms you are describing it seems like a viral infection (some kind of flu). Headache, joints ache, fever, and respiratory problems are common in this condition. Since you have a history of a week and the symptoms are back, bacterial infections of the respiratory tract as a complication may have occured. I would suggest you to have a complete blood count done, and throat secretions culture. If you have breathing difficulty, cough or chest pain, do an X-ray of the chest.  If bacterial infection is proven, a specific cure with antibiotics should be started. Until then you have to control your symptoms by a support therapy. Take Ibuprofen every six hours for the fever and pain, Vitamin C to increase the immunity strength and electrolytes (ORS orally). Have light meals, soups, and plenty of liquids. Feel free to ask again after the results. </s>
