Hi thanks for contacting HCM... Yes you could have respiratory tract infection viral or bacterial.... It could be simple sore throat or bronchitis if cough associated.... In such infection muscular pain can occur as constitutional symptom.. Along with antibiotic symptomatically management done.... Drink more water. Hot water useful rather then cold one Avoid excess fatty and fried food.... Avoid smoking.... Dust exposure kept minimum... If condition increasing with fever then auscultation for crepitation done with chest x ray to rule out pneumonia like condition. One tsp ginger juice with honey taken twice daily for few days..... Hope your concern solved.... Keeping this in mind consult physician for examination... Take care. Dr.Parth
