Thanks everyone for the quick reply. I appreciate it. I have POTS but I also have hypereflexia which is a increase in BP with any stimulant. If I have ingrown toenail,sunburn,medicines including anesthesia,constipation,UTI,any injuries can trigger a RAPID increase of BP almost to a dangerous situation. I have a cervical injury and this condition creates the hyperreflexia but otherwise my BP is 90/70 the spinal cord is triggered with the ANS and can cause a raise in BP until the problem is found (UTI,constipation) I have had it once when my bladder was over full and it was scarey BP went from 90/70 to 158/100 for about an hr. Does anyone else have this with POTS
