Hi welcome to health care magic..... On preliminary approach it seems to be viral infection in which muscle ache and bone pain can occur.... Symptomatic management done.... Do steam inhalation two times a day... Salt water gargles done .... Drink hot water.... Iodine gargles also useful in sore throat.... For congestion relief take benadryl for few days.... More water taken and excess fried and spicy food avoided ... ASO titer has to be done to rule out streptococci infection... Oxymetazoline nasal drop also useful.....Taken for three days... If still no improvement your lymph node palpation has to be done ... Auscultation also done for checking respi system.... If cough more than three week than posterior pharyngeal swab taken and chest x ray needs to be done ......... Consult physician for examination..... Take care.....
