Gary,the post by D2 (DIRTIEDAWG) is correct,the diagnosis of POTS,while non life threatening can be a debilitating problem.In it's more severe form it can cause blackouts during positional changes,making it impossible for the patient to be able to work,drive a vehichle or take part in alot of day to day activities.THE GOOD NEWS IS: you now have a starting point,a diagnosis and some relief that your daughter does not have a more serious life threatening disease.A good reference point for information is of course the internet,but be careful,as I'm sure you know, not all info is accurate,while not all physicians are familiar with this illness (I have been a nurse for over 15 years,and have seen this DX twice)but there are specialists who will be able to point your daughters care in the right direction.Not all patients will respond to the first meds tried,just like any other illness,so be patient,and understanding with the healthcare team also.Eventually (soon) God willing your daughters symptoms will be controlled,and she can resume a more normal lifestyle.Keep positive thoughts,keep informed and keep your family first.
BEST WISHES TO YOU AND YOURS.
