<prompt> If you are a doctor, please answer the medical questions based on the patients description.my husband is having erratic blood pressure, ranging from 13075 to 225110. He is also experiencing vertigo and is having problems with his stomach, acid and pain sometimes in the upper stomach or gallbladder. he has had ekg s, xrays, blood work, up GI...etc. They cannot find anything wrong. I m getting worried since sometimes he seems like he is really sick.  <response>: Hello! Thank you for asking on Chat Doctor! I carefully passed through your question and would explain that these blood pressure fluctuations can be related to an Chat Doctor. I recommend some tests for this purpose if you have not performed them yet: - cortisol and aldosterone plasma levels-urinary metanephrines for possible pheochromocytoma- thyroid hormone levels to exclude possible thyroid dysfunction. The vertigo can be explained with the peaks in blood pressure values. Anyway, a Doppler ultrasound of the cervical vessels would help exclude possible narrowing of the cervical arteries, which can also lead to vertigo. Hope you will find this answer helpful! Kind regards,
