I was referred to an acupuncturist by my naturalist for long term idiopathic neuropathy. I was told I would/should feel some relief after the first three sessions. I went 6 times and my feet were burning so bad after the 6th that I had to quit.
I was given various Chinese supplements during the 6 weeks so any improvement could have been from those. I was told by a friend that they need to use the long needle method for at least 20 sessions to notice any change. BTW, my guy used electronic stimulation with 4 of the needles.
A lot of tingling and nerve twitches in legs during the 1/2 hour treatment. I believe he used 12 to 16 needles from head to toe. I had two other Dr's perform similar treatment and those were a totally different experience: Relaxing and emotional. Due to conflicts in schedule I didn't continue with those. I can only advise that you check out the credentials and specific treatment results from the acupuncturist. I ask to talk to the patients that have been helped by them. Obviously they cant provide such but they can offer examples of conditions they have successfully treated. Keep in mind that it may work for one person but not another given same circumstances. Frustrating at best.
Wish I had better results for you.
