Y pipes and rotator cuffs

In Anchorage we had to have Ford replace a cracked Y pipe. There was exhaust getting into the cab of the truck. It's fixed, but now I have a bad rotator cuff. I think I injured it doing snake arms in March then annoyed it further when cleaning the ceiling in April when we were getting ready to move. I, Dr. Liliana, gave myself a diagnosis via WebMD. I'm taking Ibuprofen for it now. It bothers me at night sometimes.
