U will need to see a NL (neurologist) at some point but u need to find one that is well informed on Chiari and related conditions,
ICP= intracranial hypertension or excess CSF build up/pressure...a LP (lumbar puncture) is done (with care) to determine if the pressure is from CSF...they look at the opening pressure to help determine this DX.
POTS=Postural orthostatic tachycardia syndrome is a condition of dysautonomia, to be more specific orthostatic intolerance, in which a change from the supine position to an upright position causes an abnormally large increase in heart rate, called tachycardia. Several studies show a decrease in cerebral blood flow with systolic and diastolic cerebral blood flow (CBF) velocity decreased 44% and 60%, respectively.People with POTS have problems maintaining homeostasis when changing position, i.e. moving from one chair to another or reaching above their heads. Many also experience symptoms when stationary or even while lying down. A tilt table test is used to DX this condition.
EDS or Ehlers-Danlos Syndrome is a connective tissue disorder, amny with it may have easy bruising, slow to heal,and hyper mobility or double jointed.... and may have issues with mal-absorption of vitamins, minerals and even issues with anesthesia, drugs and foreign matter.....so it is very important to know if u have this b4 considering surgery where a dura patch of foreign matter may cause more issues post op.
