I was diagnosed with POTS in 2008 but my doctor thinks I probably had it since 1996. I seemed to develop it after getting the flu. My 7 year old daughter, who has sensory integration disorder, is now showing symptoms of POTS. I'm getting ready to have her tested. She misses school at least once a week due to tiredness, leg pain and poor immune system. Her sitting heart rate is 57, standing is between 97-120. When I initially started researching POTS I remember reading something about there being a possible genetic link between mothers and their children, particularly with daughters. Do any of you have POTS and your child? I'm also curious how young some of the children are because most seem to be in their teens. Seven seems very young. Do the young children tend to improve or have it for long term? Any help would be great. Having two people in one family with POTS seems unreal and hard to get my head around. I'm starting to research other disorders that may have the same symptoms. I'm curious because she is able to put her head below her heart and can spin around, both of which makes me sick.
