Cold and cough. What should i do?

Hi Since 2 weeks I'm suffering from cough, itchy and sore throat. Now I don't have sore throat. Initially I was having dry cough for which Dr prescribed me to take glencoff dx syrup & aldigesic p & rapiclav 625 tablets for 2 days bt after some days yellow mucus started coming throughout the day . Even after taking cough syrup cough  is still there. From 2-3 days I'm feeling feverish bt temperature is 97 - 98. I'm feeling lethargic. Dr prescribed me to take almox 500 and cheston cold for 2 days. I even took it bt today I m coughing too much. I m drinking lukewarm water and gargling with salt water and steam inhalation bt cough still persists. In night one side of m nose feels blocked and in morning it feels wet. Head feels heavy. From 3-4 days I'm having toothache . Even after taking medicine, cough syrup, gargling and doing steam inhalation cough still persists. Sometimes i feel it's improving, sometimes it gets worse. What should I do?
