It's just a more highbrow approach to the magic water.
Get a physio to pull at your arm.
James Rodriguez looked in awful pain during Real Madrid's Champions League win over Roma. He was pointing to his shoulder, he wasn't moving his left arm and he seemed to be signalling that there was something wrong with the joint.
For all intents and purposes, Madristas could've been forgiven for thinking they were losing their Colombian gem for a spell with a dislocated shoulder.
They only lost him for five seconds though. All it took was a tug of his arm and he was right as rain.
