Amoxicillin Causing Heart Problems?

Sorry, I posted this before I was done typing and can’t figure out how to delete it. Well, anyways, I’m having the problems stated above, as well as heaviness in chest/difficulty breathing and shortness of breath/visual disturbances like fuzziness, streaks of color or lines/random bouts of tiredness, like my eyelids are really heavy/random cramping pains all around my torso/chills/upset stomach/pressure and heaviness in my head. These problems only seem to arise when I take the Amoxicillin, but I have a really bad infection that also needs fixing. Is there anything I can do/any other medicine that would be better for me?
