In talking to doctors and looking around here, I think one of the biggest issues is that there are so many causes for POTS symptoms that doctors may have a hard time getting all the research together or all the info in one place. I'm certainly not trying to step on your doc's toes, but I came up with something for Frances that might help everyone, including the doctors. I put together a worksheet with all of the reasonable causes listed on potsplace.org, some notes about each one and what to look for, and the tests that might be used to determine if that is the primary cause of your symptoms. Here it is in excel format, ready to print out and be put in a binder or folder: POTS causes and tests worksheet just in case some of you don't have excel (I don't know if this one will print right), I've also made a PDF of it: POTS causes and tests worksheet - PDF PLEASE give me feedback, comments/suggestions, ANYTHING to make it more useful or correct any mistakes. I can't promise that it will be updated in a timely fashion, but I'll do it as soon as I can. My e-mail is gordoodle@hotmail.com I'm working on a treatment sheet right now as well. This one is a little more complicated, so it might take a while for me to get it done. It needs to include interactions and side effects. Also, an important question: While we're trying to pin down the diagnosis thing, I'm thinking about putting together a template for a symptoms journal so that people can write down how they were that day, what they did, etc. - an interested doctor might be able to get something out of it or see a pattern. Here's my ideas so far: date scales of 1-10: chest pains aarrythmia tachycardia dizziness fatigue headaches fainting blood presure and heart rate if taken, at what times... What you ate What strenuous activities you performed how much sleep you got fluid intake?? I'm not sure - it seems like a lot to keep on a daily basis, but I think it might help even if kept sporadically. Can anybody give me any tips on how to do this so it's convenient and easy to keep up? Maybe needs to ask for less info so you don't feel like lab rats some days? Let me know if there's anything I can do to improve on this! - Gordon
