If you want to go to medical school to become a Medical Doctor (MD) or Doctor of Osteopathy (DO), your undergrad degree does not matter as long as you take the prerequisite science classes. Most of us nontrads graduated with no intention to go into medicine, and then went back to school to take the prerequisite classes. My undergrad was in European History, about as useless a degree as you can get.
If you want to go to medical school, you will need to take a year each of general chemistry, physics, biology, and organic chemistry, all with labs. Depending on your undergrad GPA, you might also need to retake classes to boost your GPA to the point where you are a competitive applicant for medical school.
