I had very painful low back even could not walk well, first time when I visited there I couldn't trust cause I didn't get care like this before in Europe, but after one time of care, I can walk with much less disturbance, absolutely better, even sometimes miss request, mixed together with other mails he told, anyway fortunate I got reply quickly, If I didn't get it, would call him cause its near from my place gagman, jamsil. Only after 3-4 times I don't feel any trouble, can walk pretty much well.
