Hi all, I'm new to the forum - My overview, feel free to skip to the question at the bottom! - I've been a nephrology patient since the age of 14 - I'm 22 now. I had a previous hx of frequent kidney infections and was finally referred to a specialist where I discovered I had bilateral reflux into my kidneys - I had the deflux procedure done at 17, and then at 19 came back with recurrent infections and discovered I had large stones in my kidney. I had those removed and have been on propholactic antibiotics, diuretics, and potassium supplements since. I was constantly complaining to different nephrologists (including one at Mayo) that I'm so tired, I don't want to go out with friends, I had chronic daily pain in my back, and I had blood in my urine still on occasion without infection. I even broke down in his office crying about it. I think that my fatigue was written off with my other symptoms. The first time I passed out I went to the ER and was dx with a kidney infection, after that every time it happened I assumed it was just my kidneys again. I eventually passed out during a clinical for school (I'm a nursing student), they called a code over the hospital so several doctors responded - I have to say that was the longest I've been completely out, I had a full staff around me while I lay on the floor, a pillow under my head, and a blood pressure cuff on before regaining any conciousness. The doctor responding suggested I get a full cardiac workup, I was surprised, but I did. I had a holter showing tachycardia, some PVC, some SVT - but otherwise pretty normal. From that point I had a TTT (positive), Treadmill stress test (My BP dropped 8 minutes in and I nearly passed out), Echo was fine, and ended up getting a cardiac catheterization which showed normal coronary arteries. I had these tests done by a cardiologist, he placed me on 25mg of metoprolol, but when I was still complaining of blackouts upon standing he refferred me to an EP who added midodrine. ** My cardiologist told me I have NCS/Tachy/Orthostatic intolerance- After reading about symptoms of POTS and checking off majority of all of them, I printed the information from this site and brought it with me to my next appointment. I asked him if he heard of it and he said he had. He then told me basically that I have that, and it's all basically orthostatic intolerance? When I went to the EP, the nurse was VERY helpful as she has NCS .. but we never discussed POTS Could someone please explain to me if there is any benefit to actually being labeled with POTS vs NCS/IST/Orthostatic intolerance, would my treatment be any different? Also, should I be seeing a neurologist? I'm new to all of this, but because my insurance deductible has been met for the year I would like to get any testing done that might be beneficial for continuation of treatment before the end of the year.
