“Put these on a few hours ago and they've significantly improved my elbow pain. As an attorney, I work all day at a computer and even with an ergonomic keyboard and mouse, my elbow pain is very bothersome and swollen with repeated use. These are NOT restrictive at all, like some of those thicker elbow sleeves are, and these are also very breathable.There is a seam on the sleeve which is reflected in the photo. Personally, I didn't like how it felt on the outer side so I positioned it to my inner arm side (as shown) and I like it better like this. It does NOT roll down like some others do, which is also great.For reference, I ordered a medium. I'm 5'10â€Â, 130 lbs, and my bicep is roughly 11.25 inches (flexed). If your bicep is even one inch bigger, you could probably stick with the medium if you want a lot of compression. I highly recommend these for elbow pain.”
