Hello all, Eva’s recovery has been going well since January. Today she is in a lot of pain and for no obvious reason. Can the change in weather affect her hip replacement? She mentioned that two days ago, she felt as though she was struggling with the mechanics of moving her leg to walk but said once it warmed up after a couple of hours it was okay again. Today though as she walked upstairs she felt a ‘jolt’ and now she’s crying. Please advise.
