I had a colonoscopy procedure done today and was put to sleep. The doctor ended up doing a biopsy as well. After awakening from the surgery, I felt okay. This was done by going through the rectum. When I got home, I ve noticed my throat and neck is really sore as if the tube was ran down my throat instead of rectum, I ve not had any blood come out but my rectum is sore maybe from bowel movements perhaps. But, the front of my head has a very bad pressure to it, as if I got the lights knocked out of me. Of course I m worried and just want to know if I should be concerned or is this natural to have pressure on my head and my throat and neck (lymph nodes) hurting???
