I had a few pieces of beacon for a snack, I cooked them in the microwave and they tasted ok, but then I remembered my mom saying that they've been in the refridgerator for awhile and they might be bad. After I ate them I kept feeling sharp pains in my stomach and my shoulder. The only unusual thing I noticed about the meat was the parts at the bottom of the strips had a darker colour. Is ther anything I can do to keep my health from going bad, or is this pain stuff all in my head?
