### Patient: Hi doctor, I've been experiencing a lot of pain in my feet and they feel very flat. I'm not sure what's going on. 
### Doctor: Based on what you've told me, the required medical tests to determine if you have flat feet are examination of your foot, a plain x-ray, and a complete physical skin exam performed. Additionally, physical therapy exercises can provide relief for flat feet. However, a rectal examination and other non-OR therapeutic procedures on musculoskeletal system are not necessary. Prophylactic vaccinations and inoculations are unrelated to your condition.
