Had tennis-golfers elbow for nearly 2 years almost all the time and not from the 2 sports mentioned purely WFP,I spent ££ seeing so called therapists trying to get rid of it to no avail so looked into it and ended up getting rid of it myself. To someone who has never suffered from it they would not believe you if you told them it can actually stop you sleeping,I have been exausted and gone to bed but any pressure from the bed or pillows can keep you awake for hours,even leaning on the side of the sofa starts it off. I got rid of it in 2 weeks when I get time I'll try and do a video it's to long winded to explain on here
