Why do I still feel sick after taking medication for strep throat?

Feeling sick after taking medication for strep throat could be due to several factors. It may take time for the antibiotics to effectively fight the infection, typically 24 to 48 hours. Additionally, symptoms like throat pain and fatigue can persist even after starting treatment as your body recovers. If symptoms do not improve or worsen, it's important to consult your healthcare provider for further evaluation.
