Hi, my sister was diagnosed with LUPUS about 4 years ago. Over the last 4 days her legs have become extremely painful, so much so she is struggling to sleep because of the pain. She is taking Ibuprofen and Paracetamol but they dont seem to be helping. She says they feel really tight and she cant bend them. Walking is painful and she is just so tired but cant sleep because of the pain. Does anyone else suffer from this, is it LUPUS related and if so do you have any advice on how to ease the pain and how long does it last?
