Yesterday I took a 875 mg of amoxicillin, it is a BIG pill. At first it got stuck and I sorta panicked, I cut it in two and tried again. After swallowing it, I felt like I had swallowed air and since then I have had chest and back pain. It hurts when I swallow, but it does not seem to be heart related. I cannot get the air bubble to move. Should I be worried or what can I do to relieve the pain? I ve tried tums, nexium but no relief.
