WHAT IS GOING ON?!?!? My sister's leg was steadily improving and we were both so encouraged....and then late in the day on Sunday (or was it Monday?) something else started happening and is getting worse. I am having trouble keeping up with when everything is happening. One thing gets better (or almost) and another immediately sets in. She is hurting on both sides (toward her back, in the rib area), but worse on the right side. She hurts when she turns over, raises her arms, reaches down or inhales. She has no fever. She does have a productive cough (and coughing is very difficult...as in also painful). I have checked pnuemonia and pleurisy symptoms, but both mention fever and dry cough. I have found where RA can affect lungs (??). Could it be the mtx?? I am thinking she needs to get admitted to the hospital for observation until all this craziness gets better under control. Am I wrong? I really do not think a single doctor has understood what all she is really dealing with...nor what this is doing to her mentally. Advice...please!
