Legally, it probably would not make ant differanc that he had two differant ailments. It would be better if he could get enough meds from one doctor to cover the amount of pain he is in, or better yet, get into pain management theraoy in order to get stronger, longer acting medications. He needs to weight the risk of his possibly getting caught with his pain and what he wants to continue to do about it. Because either way it works out, he is, in fact, getting the same med from 2 sources. I am sorry to hear of his pain.
