They told me most likely I'm more sensitive to needles that's y I ouch so much. I can only sleep ten mins after the needles go in. Initial part is always painful for me. Dr zhao told me once that sometimes she wil push the needle further in so it wil b more effective. And when I asked y the first time not pain second time pain she replied that could be the different sizes of needles she uses . I always thought there is only one standard size of needles!now that I am with dr zou, dr zhao accu is really not as painful . I stayed wif dr zou as I bpf once while seeing her and her charges is much more reasonable . $30 per sessions as compared to more than double the price when I go raffles TcmActually my experience is that accu is suppose to be relaxing and not very pain. At most a bit of small prick sensation when needle go in and plus slight suan suan. If it is pain, u have to tell the physician.... the physician will readjust the needle until is not pain. By right is relaxing until can sleep type then is correct.
