About fifteen years ago, I pulled a tick out of my leg and went about my business. After a few days, it got irritated and ugly looking, complete with a ring around it. I went to the doctor, and he told me not to worry about it and sent me home. That weekend, my wife had to take me to the ER. I couldn't hardly get out of bed. The dr. at the ER told me if I'd waited a day or two, I would have died. Apparently Lyme disease can cause heart failure. You guys can scoff all you want, but tick bites are nothing to just blow off as nothing. Watch them carefully, they can and will kill you if you miss the symptoms.
