I have a dry cough which seems to be getting worse. i mainly cough at night. i am using vicks acta plus. my husband thinks i need an antibiotic. my body is sore from coughing ?

You may need an antibiotic but most coughs are not bacterial infections needing that treatment. However, the only way to tell is to have an in-person medical evaluation so that you can have your ears, throat, nose, and most importantly, your lungs examined. You may also need an X-ray if the doctor thinks it is necessary...but the first step is to be examined.
