Just throwing this out there for discussion.... Im a righty. Have dealt with some elbow issues in the right elbow. It seems to have been alleviated over time with some racquet changes (many) and some working on technique as well (hitting out front). Recently I have had the same symptoms in my left elbow. Normal TE symptoms but strangely in the left elbow. My thoughts...I do have a 2HB and also BH slice. I dont hit enough using my left arm that would cause issues. However, I do use my mobile device alot, often laying in bed, emails, games etc. throughout the day as well (not in bed). My thinking is that somehow the way i hold my phone or use my left arm over prolonged periods in some strange position that would cause similar TE symptoms. Who knows, maybe I sleep in some weird position. Just curious if anyone else had a similar experience with TE type symptoms and discovered that it wasn't actually tennis related.
