Had my 1st treatment 3 weeks ago & it was EXTREMELY painful. The needles were tolerable although they did hurt, but a couple of hours after tx, I had flu-like symptoms & legs (had front & back of thighs done) were so painful it hurt to sit down. Could not return to work that day & the next day everyone thought I was sick. I am, however, already seeing a little bit of results although I was told that I wouldn't after only one treatment! That is encouraging news since I was convinced I was poisoned & beaten! I will do this again but will take pain meds prior to going to doctor & Nyquil when I get home to try to not have the same experience again.
