Pain and disruption of routine

Happy New Year!! Sorry it's a bit late. 

To start off with, my daughter, Chloe, is doing amazingly well and I am so proud of her. She has been such a great help round the house, like always, but especially now since we are having a new kitchen being fitted. Years ago, we had an extension done and that was just absolutely horrific due to the meltdowns it created. Today, she is absolutely having so much fun pretending to be camping since we have no kitchen so can't cook, wash up, etc. There is such a huge difference in her and I love it! 

Over the past few months, so much has happened for her but she has taken it like a champ. The only thing she is currently struggling with is the pain she has been in for years. This pain has only gotten more frequent and worse. At last, the doctor has taken a blood test which can back clear so told us to keep a diary which we have done for the past month. We are going to go back soon. However, in the meantime, does anyone know of any stronger painkillers she can take since none have had an effect. We've tried paracetamol, ibuprofen, panadol, and anadin. Does anyone know what could also be the cause of this pain? 

If there are any tips we can try to just reduce the pain, even slightly, she would really appreciate it. Thanks
