Acupuncture for hypertension

Currently I am on multiple of 3 BP pills for 6 or more depending on how high my BP goes, and 2 of 1 relaxent pill.
Is there any value in getting acunpuncture to lower my BP. I'm only having a problem with the stystolic number mainly ranging between 150 and 220. If yes, is there a good site to go for a qualified acupuncturist for hypertention in the Detroit area?
Also, I've had all the tests listed on webmd and more for hypertension, nothing was found wrong over the last 15 years. I'm wondering if a Cardia Catherization would be appropriate?

CArdiac cathteterization isn't very helpful in the setting of HTN.  I wouild suggest getting a renal US to rule of renal artery stenosis.  Otherwise, if all other tests are normal, you probbaly have essential HTN.  I would recommend seeing a nephrologist who usually specialize in treatement of difficult HTN cases.  Accupuncture won't hurt but I am not sure that it will help.

I had a 64 slice CTA Renal Arteries test in January and it was fine. Is that the same as a renal US to rule out renal artery stenosis? If yes, would you still recommend seeing a nephrologist?
Thank you Velan.
