I Went To Urgent Care Few Days Earlier, Was Diagnosed

I went to urgent care few days earlier, was diagnosed with Peritonsillar cellulitis. And was given an antibiotic, cephalexin. I have been taking it lately, but as it seems the antibiotic is what making me have dizziness. I went to emergency room- another doctor said she don't see any infection, that was a day later after I went to the urgent care. She also identified that I have unknown allergic rhinitis and post-nasal drip. But she said continues taking the antibiotic and also gave me allergy medicine. Allergy medicine actually helped a lot, so I felt that antibiotic wasn't necessary in first place. Not sure where the opinion stands.
