Suggest Treatment For Sore Throat And Body Pain

For the past two days I have had a minor scratchy throat (which I attributed to eating too much crisps) Today I woke up with a sore throat and around midday, I began to have aching pains all over, firstly when I was washing my hands. It has now been several hours and after sleeping for two hours, my whole body is still aching, still feeling very tired and loud noises hurt my head. I still have my appetite and only have to occasionally blow my nose (with a bit of phlegm).
