My son received his letter from DoDMERB to call and schedule his eye exam and medical physical. He called the eye doc and made an appointment with no problem. When he called to schedule the medical physical with a Concentra clinic, he was told that he did not need to make an appointment, that those were done on a walk in basis. Has anyone else run across this? It seems kind of odd that this level of exam would be on a walk in basis...? Any thoughts? He doesn't want to mess this up and the DODMETS web site has told him to enter his appointment dates & times.
