(Concern) Is it bad to get injections too often?

I have never had any aversion to traditional Korean medicine treatments since I was young.

I took herbal medicine well, took the tonic well, and also received acupuncture effectively.

Two years ago, I sat down and when I stood up, my knees hurt so much I couldn't walk, so I received treatment at several orthopedic clinics and spent quite a bit of money.

But the only improvement was on the day I received treatment... I still couldn't walk properly because it was too painful to sit and stand, and I limped.

Then, by chance, I received acupuncture at a traditional Korean medicine hospital based on a recommendation from someone nearby... and amazingly, from the day I received the acupuncture, the pain completely disappeared and I started to feel better. After that day, for a while, I received acupuncture every day... and after some time, I went to get acupuncture 2 to 3 times a week.

I was okay for a while after recovering, but lately my knee has started hurting again.

I want to get acupuncture... but I think there are people who say it's not good to get acupuncture too often...

How often should I get acupuncture treatments?
