I have numerous Diagnoses including: POTS, Autoimmune Disorder, AV node re-entry tachycardia (which was ablated), irritable bowel syndrome , chronic inflamatory disorder, there are others but my latest is Reflex Sympathetic Dystrophy Syndrome (RSD) it is also known as Complex Regional Pain Syndrome. I have had apx. 18 surgeries for varies reasons, I currently am getting sympathetic nerve blocks which are helping to alleviate symptoms of my RSD. My 20 year old son was diagnosed with POTS in 2008 he was involved with Dr Chelimsky study on the link with dysautonomia & the affect on GI. In Sept 2011 my youngest son started having symptoms of POTS we are trying to get him in with Dr Grubbs (which is who my 20 year old & I see) but since it takes sooo long to be seen be him he is being cared for by U of M cardiologist.
