Yes they are very good. Beside the needles are quite small.
Recently I had a knee massage due to some pain and it was quite effective. The amount of sessions you would have to check with them and the seriousity of your issue. For the price it is way below I once paid at a clinique in Flic en Flac (maybe I got the tourist rip off there, 5 mins seeing the doctor = 1000 RS)
Meanwhile I would refrain from saying doctor, not because they are not, but I guess it is (due to some inexplicable reasons in the western world) not as respected as pumping pills into the patient. Nevertheless they are great therapists, to not post any commercial here I will send you the rest as a PM.
