Has anyone done acupuncture? Have you had positive results? Did you have any negative side effects?

I am seeing a new neurosurgeon who has recommended acupuncture, they swear by it and told me that I would notice improvements right away and that after 2 sessions I would see how amazing it is and be willing to pay to continue.

Well I have only done 1 but I have suffered huge since and I don't know if it is because of that. It was a week and a half ago and I am super dizzy, nauseous, headaches and pressure, extreme fatigue, anxiety and just feeling so down. I was starting to function okay but this just feels like I have been pushed so far back.
