Acupuncture Questions?

I'm getting acupuncture for the first time tomorrow and I was wondering what actually happens usually, other then the needles.
And what do you wear, or does it matter?
the acupuncture is to help my stomach, if thats important.

Thanks!

I received an injury to my Ulnar nerve which left me with pain in the elbow along with pins and needle in my fingers.

I persevered with convention treatment, as I am involved with sports medicine and clinical nutrition. anyway while walking through a local shopping centre I cam across an acupuncturist.

I walked in explained my problem, they took me into a room where I laid on a medical couch and was asked to relax.

The acupuncturist then proceeded to place needles within various parts of my arm and neck. There was no pain or discomfort.

The needles were moved rotated (twisted around) this took about ten minutes. I was then left for 20 minutes, in a semi dark, during which I must have dropped of to sleep. I was aroused from my slumber, the pain in my elbow had reduced dramatically and the pins and needles had stopped.

I had two further sessions which eliminated a problem that I had been suffering with for over 18 months.

As I said I walked in from the street. I had been dressed casually with jeans and sweat top and trainers

wear something comfortable. If they need you to remove your clothes they will provide a gown just like at any doctors office.
