I started a new job 3 weeks ago, I am an assembler for a well known supermarket in their distribution center. My job involves taking a product on a pallet from one area of the warehouse and placing them in cages around the warehouse using a pedestrian powered pallet truck. I'm only 3 weeks in an my hands are knackered, i have constant tingling in all my fingers, I wake during the night to find them feeling dead which is really painful, I can't hold items for longer than a minute anymore otherwise the tingling gets worse and more painful then the throbbing starts, I'm losing my grip all the time now its just slowly getting worse. I have worked in warehouses before and this has never happened so why now, would it be worth a trip to the GP, is there anything I can use to help prevent it getting any worse?
