Thou shalt avoid draughts, yet ventilate thy room oft, just get somewhere else during the process. Get some antiseptic and soothing rinsing for thy throat, avoid cold and extremely hot food and drinks. And consult a local medic to exclude bronchitis or pneumonia. Besides, considering thy symptoms, the sickness could be of viral, not bacterial nature (if 't be true thou dost have running nose and/or much expectoration not, tis speaketh for the viral variant), thus demanding for different treatment.
