Getting prepared on your doctor's appointment

I go to the doctor's with my husband because he is not feeling well. We've spent five hours altogether with testings and scans which by the way five hours is really a pretty short time these days and have all the testings done. Its a good idea if you can to get the earliest appointment and take a snack with you if possible so you don't starve at lunch time waiting around the waiting room for test results. So they did all these tests blood work, x-rays, cat scan and everything comes back great. I guess we should be happy that everything shows good but my husband still feels bad so they scheduled a colonoscopy to make sure nothing is going wrong.
