I have Discoid Lupus and Sjogrens . After taking Hydroxychloroquine for several weeks I felt heaps better until last week. The awful dry retching cough I had came back as did fatigue and aches all over. I try not to start coughing and keep it at bay by sucking lemon sherbets and drinking lots of extra water, Is this a flare and if so will it pass? Grateful for experiences and advice.
