Pain reliever for syringes comprises a tubular sleeve (4) that is pressed against the skin and through the syringe (2) is inserted. The sleeve has a concave tip (6) with radial or concentric projections surrounding the hole through which the needle (3) emerges, designed to stretch the skin round the needle's entry point and make the pain of the needle penetration more bearable.

The other end of the sleeve has a grip (8) that is held between the finger and thumb by the person giving the injection, and a window for viewing the syringe and controlling the amount of fluid injected.
