When student Molly Doyle had a pain in her hip she initially passed it off as a pulled muscle, but when it got more severe she became worried it was something more serious. The 22-year-old student, from Colwyn Bay, began to experience "strange flare ups" of hip pain that would come and go over a few days.
At times, the pain was so severe that she could barely walk, but within a few days her symptoms would subside and she would be "completely normal".
Molly, who is a second year student at Liverpool University, said the "on and off" nature of the pain initially led her to dismiss what was happening as she was otherwise fit and healthy.
