What causes joint pain, headache, and a running nose with blood during sneezing?

Hello,

Welcome to icliniq.com.

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.
