◆ Patient testimonials
[Female, university student in her 20s]
In the past few years, before my period, I would feel depressed, irritable, and fatigued, to the point that it would affect my classes and part-time work. In particular, during the week or two before my period, I would feel depressed every month, thinking, "Here we go again..."
I heard that acupuncture was good for me at a time like that, so I started coming here. At first I was skeptical, but after a few treatments, I've noticed my physical condition improving little by little, and I can feel my premenstrual discomfort easing up.
Now, I am not as easily affected by mood swings as I used to be, and my daily life is becoming easier.
I'm really happy that there are more and more months where I can think, "This month was really easy for me." I want to continue doing this.
