I Had Bronchitis A Few Weeks Ago. I Was Given

I had bronchitis a few weeks ago. I was given and antibiotic, an inhaler, and put on a steroid. I have finished my meds, but I don’t feel good. I have a dull headache, I’m tired, and I still have a cough. I am constantly clearing my throat. I have tried nose sprays and they don’t seem to work. I have hot flashes and dizzy spells every so often.
