I get very hard palpations makes me feel as if i'll vomit, normally lasts 10-20 sec. this time last 5 min. bp spiked then went down after. causes?

R/o pheochromocytoma: While these symptoms are odd and not terribly specific, there is a rare tumor of the adrenal gland which can cause similar symptoms. You should see your physician and tell them of these symptoms. They may require you to submit 24 hr urine samples to check for the metabolites of this tumor, which can cause labile bp and nausea. That said, it is unlikely that you have this,
