Yesterday my rheumatologist diagnosed me with Mixed Connective Tissue Disease )(MCTD). I spent part of today researching my new dx. My understanding right now is that it is an overlapping of systemic Lupus Erythematosus, Sclerodema, Polymyoositis and rheumatoid arthrtis.. Clearly this explains my pain. Has anyone else received this diagnosis and if so, can you share your experience and am I on the wrong Message Board because as far as I know I still have Fibro. (sigh) Thanx I was told to avoid red meat, watch my salt intake, and drink lots of water. She did an extensive blood pane.
