I'm a 23 y.o. man and I havent gotten a checkup from a doctor since age 10. Someone told me that it's important to go in case i have some kind of illness that I don't know about. Over the years, I've had bouts of nerve pain, abdominal pain, lower back pain, a hernia, broken finger, broken wrist, and some nasty infections. None of the times have I been to the hospital. my body just healed on it's own. So I feel like I should be fine in case there's something wrong with my bloodwork. But is there any specific reason why I should get a checkup that would cause permanent damage if I dont catch it early enough?
