I am in a bad flare right now. When I woke up this morning my legs feel very weak. Like I am going to fall with every step I take. My knees feels like it is moving side to side. Like it is not satble. When I walk it feels like there is fluid in my joints. Could there be fluid building up in my joints and could this happen over night. There is no more then ususal swelling in my knees.
The answer is yes. Although not usually the case if you are being treated, flares can be sudden and severe in onset.
