Hello, my wife is 44 years old and has had Rheumatoid Arthritis and Fibromyalgia for over 9 years. Recently she has been having sever pain in her chest and shortness of breath, her doctors have tested her heart and have ruled that out, she has an appointment with a pulmonary specialist tomorrow. However, today she is very weak in her lower extremeties, to the point of not being able to walk, and has been having numbness of her left hand.
Hello! Thank you for asking on Chat Doctor! I understand your concern, and would like to explain that, facing her doctor has ruled out cardiac issues, further investigations should be performed on alternative directions. First to rule out any Rheumatoid arthritis exacerbations. A physical exam with some additional lab tests, like complete blood count, PCR, ESR, RF, X-ray films study, etc. are necessary for the differential diagnosis. Meanwhile, check her blood pressure and try any anti-inflammatory medications. If the complaints persist, you should visit an ER doctor without delay for some preliminary tests. If after all diagnostic work up, nothing new results, then an optimization of fibromyalgia management should be implemented.  Chat Doctor.  You need to discuss with a specialist on the field (neurologist) on that issue. Hope to have been helpful to you. Greetings!
