I started few weeks ago having a low back pain, I felt pain only at the low end of the spine (all the time, moderate pain) plus on the left side of the butt (not lower, only when moving the left leg, moderate pain). Only pain, no tingles whatsoever.

I went a week ago to see a chiropractic doctor who said after only touching my spine and inspecting visually the extend of my leg movements (no x-rays) that I have a lumbosacral dysfunction and I need few strong pushes to move few milimeters back the bone that 'sits' between the last vertebra and the big bone (sacrum I think it's called). After the first 'push' I took an ultrasound therapy of 5 minutes on the same low back area then left him w/o feeling better or worse at that time.

After approx. One day the low back pain was almost gone (i felt it only once in a while), but I started to have permanent tingles especially on the lower end of my both feet, w/o any pain anywhere; the tingles are sometimes going up to the knees, I can feel other nerves all over my body pinching me sometimes.

So now I got rid of the low back pain but got into another possible problem. Are these tingles the (side)effect of the ultrasound therapy ? Are they normal, since they are not even in the treated area ? Did the doctor actually by pushing a bone out of position touch a nerve or smth. And now i'm in a bigger mess than before ?

I am supposed to return to him for another 'push' us therapy, but I would like a second opinion.

In case it would help :

i did not sustain any accident and/or any other event to correlate the back pain with, I did not take any pills till now, i'm working around 8 hours per day sitting on a chair in front of a computer since 10 years ago, I am 26 (twenty six).
