If you don't mind looking like the Hunchback of Notredom, this Airo messaging backpack will provide you a relaxing massage without having to beg someone for it.
Now that I think about it, having someone walking behind you rubbing your shoulders might not be a good look either.
If my little German translational skill doesn't fail me, Airo features four engines that massage the back and shoulder area, an integrated heat and vibration functions to relax your sore muscles. It includes three massage stages that you can choose with the control buttons.
The vest is made from Neoprene, comes with a 230V AC adapter, and sells for â‚¬40.
