Can't Make it Better

I am so worried about Robbie. His legs and back have been causing him so much pain recently and I don't know what to do to make it better. Last night he didn't know what to do with himself, he couldn't sit down, but he couldn't stand up or walk around comfortably either. He described it as a constant unbearable throbbing and it made him really bad tempered. The most frustrating thing is that all the doctors can do is offer stronger combinations of pain killers but it doesn't work. I want him to go back yet again to see a consultant, there must be a better way to manage the pain, but Robbie seems to have given up hope of getting it sorted out. He says that they do tests and more tests but they never make it any better. Last night he didn't come to bed at all because he was too uncomfortable and he just couldn't settle. He can't go on like that!
