So I was having internal gas problems in the intestinal area (left side of belly) and I took some medicine, Equate Extra Strength Gas Relief Simethicone 125mg (not that big of a dose). Afterall, I've taken bigger doses (about 500mg) for allergies. However, something else happened. I developed a huge fever, like getting really hot, and feeling extremely weak. I started feeling cold and to shake. Now, my throat is raspy. What just happened?
