Hi there. I have been struggling and am grateful to have found this support group in hopes of some clarity. For years I’ve had random lightheadedness upon standing. It was infrequent and I just shook it off for a long time before finally asking the doctor about it. I was told at that point that I had ortho static hypotension and just needed to move slower. I let a couple more years pass before it started happening several times a week. I finally brought it up to the doctor again as I was also getting severe headaches and experiencing light sensitivity, and this time I was told my BP and HR actually increased when I stood up. I was sent to a cardiologist for testing. In the meantime, as a possible “POTS” diagnosis was being researched I started to realize I had other symptoms for years that I just figured were my “normal” such as stomach issues, constant thirst and frequent urination, anxiety/shaking, shortness of breath, chest tightness/pain and random pain throughout my body. Now my symptoms have changed and worsened, or maybe I’ve just become more aware. In attempts to monitor my heart rate, I purchased a blood pressure monitor. What I discovered kind of shocked me. Many people mention with POTS, the irregular heart rate. With orthostatic hypotension the low BP upon standing... nothing quite makes sense to exactly what I experience. For example, when I’m resting my BP is anywhere from 80-100 over 45-75 (very low!) My HeartRate is typically all over the place, sometimes resting at 60, sometimes 80. The moment I stand up, my BP increases by 20-40 points- both numbers. My HR usually increases 20-30 upon standing. A simple task such as changing my clothes and blow drying my hair (to get ready for work) puts me at a BP of 153/105 with a HR of 140. It’s so irregular and changes every time I move. This is a daily occurrence. It scares me to think what kind of damage this is doing to my heart. Other symptoms include headaches, light sensitivity, seeing flashes/spots, noise sensitivity, stomach issues, nausea, loss of appetite, chills/cold often or unable to remain a comfortable temperature, Cold hands and toes, shaking, pain, ringing in ears, lightheadedness upon standing, Heart palpitations, fatigue, chest pain, shortness of breath, brain fog, frequent urination, never feeling that my bladder is empty, constant thirst/dry mouth-I have water by my side constantly... Does this sound like autonomic dysfunction? Can anyone relate to these symptoms? I really would like to understand what type I have and possible other conditions causing it but I don’t know if my instincts are correct. My primary wants me to now see an electro physiological cardiologist but I’m not sure if that will be another unnecessary visit. A main concern is that I failed my tilt table test... can I have Dysautonomia with a negative tilt table? Nothing was found with a 48 hour heart monitor other than the fluctuations of my HR, with no explanation of why.. Stress test was fine, MRI and MRA were fine.. all blood tests came back normal. it’s all so confusing. I would really appreciate any insight you might have to give. And I apologize for sounding so pessimistic.. I’ve been handling this basically on my own and I’m feeling defeated Thank you.
