No rheumatologist that i've been to have been able to diagnose my growths on my ankles and writsts i live in south-africa.

Sounds interesting: That sounds interesting. What parts of your ankles and wrists are affected? The achilles tendon perhaps? What do they look like? Here is a condition worth considering- xanthoma? http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0002418/ It would be useful if you attached a photo, if you do not mind.

Workup/mgt.: It would be helpful to have more details. I would suggest also screening for autoimmune disease and Lyme Disease, in addition to a comprehensive metabolic panel and ESR. There are also imaging studies which may help in determining the underlying cause.
