Suggest Cure For Bronchitis

Hi, I had bronchitis a few days ago, took predisone for 5 days, antibioctics for 5 days, inhaler for a few days. then I felt better. last night i developed terrible pain all in my head, neck, head felt very heavy, pain under my arms and back. I felt pain when I touched my face. Very weak. Basically I felt I had been beaten up real bad. Mom called dr. she put me on 600 mgs advil til morn. went to dr. this morning, he said i will hurt real bad for three days he gave me tylenol with codeine. he said it would get worse before better. it is some type of virus you get when you are gettng over an infection. does this sound right or do you have any other diagnosis. I am 18 years old.
