I hurt my back last week, have been having physio for it, and have been prescribed naproxen and diazepam. It's improved a lot, but I'm still in so much pain that I cannot do anything for more than 20mins or so, before I have to change position or go for a rest. It's debilitating. If I continue taking the diazepam as prescribed (3 x 5mg daily) it will run out on Thursday. Friday we are going on holiday and have a 5h drive to get there. I'm dreading it. What do I if I'm still in pain while we're away? We're staying in England.
