I caught fever last week. Symptoms are temperatures above 101F, body stiffness and pain, weakness, sometimes nose gets clogged (this happened in last 3 days out of the 6 days of my illness). I am taking Ibuprofen 400mg tid, cefixime 200mg tid and a drug combination (paracetamol 500mg, chlorpheniramine maleate 2mg, phenylephrine 5mg) tid for 1 one week continuously. Fever keeps going and coming every 8 hours but not getting cured. It is communicable as my wife also caught it yesterday. What can be the possible reason? How can this be cured?
