i have joint hypermobility syndrome and have had many medical problems (not related to my JHS) over the past 4 years, since the birth of my twins. they have included multiple neurological problems such a parathesias, pain, sleeping problems, weakness, visual disturbances, fatigue, gait diturbances, etc. over the last couple of years i have been having a horrible problem with being lightheaded and feeling like my pulse is racing. it mostly happens after i have been standing up for about 15 minutes or so and i will suddenly start feeling like i am going to pass out, which i have a few times. i have learned now to sit down when i have the feeling or i will fall down. i have "whited out" 2 time while driving and was fortunaltey able to pull off the road or stop my vehicle before i could no longer see. i have also noticed that i have a problem with swelling in my feet up to my knees that is pitting. i have seen multiple neurologists and other doctors and was suspected of having MS but have basically been told there is nothing wrong with me. recently i was seen by a cardiologist and did a 2 week event monitor. i was told my echo was normal and that my monitor showed my heart rate was anywhere from 80-150 (i made a point to do NO physical activity during the monitoring process) but was also told that was normal---doesnt seem to me a HR of 150 iss normal but i did not see the actual reading. i had a tilt table test and was symptomatic (felt like i was going to pass out and became very fatigued while upright and after) but apparently on the monitor i was not becasue i was also told that was normal. i dont know what else to do but my family doctor can only help me treat some of my symptoms, she is not a specialist and we are both at a loss. who else do i turn to. we are military and it is hard to get good referrels. any help would be great. i am getting very tired of being lightheaded and am afraid i am going to hurt myself or someone else if i do not get treated. i almost fell on top of one of my 2 year old preschoolers the other day. if a chair had not been near by i could have hurt the poor child. i have heard that POTS can go along with EDS/JHS...can you have it without it showing up on a regular test??
