Sinusitis
"Started taking clindamycin for a sinus infection. On day one, I took one pill at breakfast and one at lunch. When I took one pill at dinner, I was having difficulty swallowing. It felt like there was something stuck in my throat. Also in my sternum area I felt a tightening. I didn&#039;t know what was happening. The next morning I looked up the side effects and difficulty swallowing and tightness in the chest are listed. I switched to a different antibiotic and will avoid this one as it obviously affects me."
