New Member with Limited Scleroderma in UK Scleroderma Posted January 14, 2011 Hello. Have you got an overlap with it? I have fatigue but I have R.A as well and it's part of that. I have scleroderma, could be CREST. You might have a little something else as well. Check your CRP (C-reactive protein) and ESR (erythrocyte sedimentation rate) levels and check your iron levels as they will go down if you are flaring with something. Chris.
