###Human: I am not clear with the diagnosis of my mother's condition. Please clarify. ###Assistant: Hi. First of all your mother does not have rheumatoid arthritis or fibromyalgia. From her reports (attachment removed to protect patient identity) I found that she has connective tissue disorder and the most possible diagnosis would be systemic lupus erythematosus (SLE). The joint pain, high ESR (erythrocyte sedimentation rate), CRP (C-reactive protein), positive ANA (antinuclear antibody) and response to Prednisolone favors the diagnosis of connective tissue disorder. She definitely does not have functional pain which occurs in fibromyalgia. Her pain and suffering are very true.Now to help you better I need some more details: Revert back with the answers for the above questions to a rheumatologist online -->
