Brief Answer:
Paragangliomas

Detailed Answer:
Pheochromocytomas and paragangliomas are catecholamine secreting tumors that typically produce the type of symptoms you are reporting.
Paragangliomas are similar to pheochromocytomas except that they are found outside the adrenal gland in various places such as inside the belly or neck area.

Further there are neurological conditions such as dysautonomia (also called autonomic dysfunction) which is a disturbance of the autonomic nervous system which can also have swings in blood pressure from high to low

Thank you for your reply. Can you please specifically list diseases/conditions within dysautonomia that share symptoms of pheochromocytoma? What else can cause extreme high blood pressure surges (250/160) and blood pressure falls (48/35)? Thank you.
