I just finished a round of antibiotics, sufatethomoxazole, fluconazole and prednisone on wed aug 30 for sinusitis, bronchitis, uti, and yeast infection. I am still not well. I am lethargic, have a headache, haven't been eating correctly. my neck hurts, I am light headed, sure I still have a yeast infection, can't sleep and my vision is fuzzy. Should I see my doctor?
