I don’t understand why it stresses you out…
It shouldn’t be used to treat candida but the general health of your body. I have not met anyone who hasn’t had a positive experience from an acupuncturist!
In my opinion you may not be going to someone who is skilled enough; try out going to someone who has done it for 20-30 years! There are different types of acupuncture as well, french-indonesian acupuncture, chinese (2-3 kinds), and some other ones.
Sounds like your new acupuncturist is much better!
