A compression sleeve should feel firm and snug noticeable but not painful. This is the compression working as intended. The sleeve should not cut into the skin, leave deep marks, cause numbness or tingling, or restrict blood flow. If the limb turns blue, white or numb, remove the sleeve immediately it is too tight and you need to size up. A well-fitted compression sleeve feels supportive and gradually becomes less noticeable as you wear it. If you're new to medical compression, it's normal to find the fit feels firm initially most people adapt within the first few wears.
