I am a 33 yr. old male. On 3/22/12 I had a colonoscopy done for a suspected polyp . Luckily it turns out I only had external hemroids. Nine days later I came down with a sore throat , nausea, constipation , fever and chills. I am a little concerned, because these are symptoms of a perforated colon. I have not experienced any stomach pain , and after three days my temperature has come back down to normal. though I do still feel nausea. Should I be concerned that my colon may have become perforated during the colonoscopy or am I worrying to much like I sometimes tend to do.
