Frustrated

Well I am completely frustrated....again. Joey and I have been fighting every night , he doesn't look happy. he always has his ears pinned at night when I try to do any thing with him. What do I do, he is just crusty ever since Dakota's accident. I love him to death.........but. I am thinking of getting a vet in to check him over. He doesn't like to be brushed anymore. I never hit him, or abuse him, he gets treats almost every night. My plan is too stop with the treats, get some peppermints, maybe he has a sore belly, and just keep touching him with my hands, I just recieved some massage books but haven't read them yet , I'll try the massage tonight and see what happens. I just want him to be happy and healthy, and most of all I want to be able to ride him again.
