I have had accupuncture several times. I think its effectiveness depends on what you are being treated for. I have a nerve disorder and it didn't help it but it helped my periods and insomnia. Insurance generally doesn't cover it but I never let what I do and don't do medically to be determined by what insurance does and does not cover. My health is to important to me. Of course, when you have a chronic disease, you will do just about anything, regardless of the cost, if you think it might make you better.
My accupuncture treatments are usually $60 a treatment.
Again, whether it works or not truly depends on what your ailment is.
Good Luck
