Brief Answer:
See an endocrinologist

Detailed Answer:
Hi XXXXXXX thank you for using Healthcare Magic. Your results and symptoms are consistent with a pheochromocytoma, which is a tumor of the adrenal gland. The adrenal gland produces a variety of hormones, including stress hormones (eg, cortisol), and another part of it produces epinephrine, dopamine, and norepinephrine. These latter act as "flight or fight" hormones and create symptoms such as you are describing.

Pheochromocytoma can be associated with other endocrine tumors or may just be solitary. An endocrinologist would know what other tests to check. He or she may also know specific medicines that will help with the overproduction of these hormones while you are having an investigation for the definite diagnosis. Ultimately you are going to need imaging studies of your adrenal glands and possibly surgery.

For now I recommend you get in to an endocrinologist very soon. Pheochromocytoma can cause sudden high increases in blood pressure that can be dangerous. Was it your private doctor who ordered the urine test? Ask that doctor to advise you on the next steps you must take. He or she may want to initiate further studies while you are getting the referral. You also need to keep a close eye on your blood pressure.

Hope this answers your query. If you have further questions, I would be happy to answer them.

I generally see a nurse practitioner.Tests were done from online lab. urine test. Pain management doctor had prescribed Cymbalta to try for the muscle pain issue. After the reaction to the Cymbalta-same symptoms but much worse I looked into the ingredients and noticed the norepinephrine reuptake inhibitor. Which I was not familiar with. Did some research and started thinking I should probably look at the adrenals.
Thinking she might think i was crazy I found the online lab to test the adrenal hormones. I know I have a 4-5 cm cyst on my left kidney. Could that possibly be the source of the excess hormone? She is wanting to send me to neurologist for the muscle issues and I was thinking I should be seeing a endocrinologist at this point?

Brief Answer:
Would see the endocrinologist first

Detailed Answer:
The more urgent problem is the possible pheochromocytoma. The muscle symptoms may be a separate issue or could be related. The endocrinologist would be better suited to make this determination.

The adrenal glands sit atop the kidneys. Possibly the cyst is located nearby and is actually in the adrenal gland. Or it could be some ectopic adrenal tissue in the kidney. This obviously deserves further evaluation with more imaging studies.

Good call on your part. Adrenal hormone problems are uncommon and often missed. You could talk to the nurse practitioner, inform her of the results, and ask for her advice and a referral. But get an appointment with an endocrinologist soon. Hope this helps.
