Hello, Welcome to HCM, As you had malaria for which you have been advised antimalarial drug for condition and you have taken the treatment for a week following which you are having generalized body and muscles aches. These symptoms suggest that you may be having viral infection which is most commonly associated with post malarial condition. The antimalarial drug will reduce the immunity which leads to easy access to the viral infection and produces all these symptoms. These are self limiting and it will come down by itself and nothing to worry. I would suggest you to take protein rich diet and diet rich in vitamins to boost up the immunity. Thank you.
