Need more information on antibiotic effectiveness

Patient: I developed strep throat a week ago today. I was put on Amoxicillin and took that from Frirday-Tuesday. After seeming ineffective, I was switched to Keflex, which I took for two days before being switched to Clindamycin. I have now been on that for 31 hours and do not feel any better. When can I expect to feel better and when will the swelling and bacteria go away in my throat?

Symptoms: Throat pain, ear pain, difficulty swallowing
