Is pharmacopuncture effective for back pain?

Due to the nature of my work, I sit for long periods, so lately I've been experiencing some lower back pain.

I am sitting on the sofa at home, and I feel like my lower back hurts.

I get up from my seat once every hour to do some light waist rotations or stretching, but I have mild pain in my lower back. The pain isn't severe, but I'm a little worried..^^

It is said that pharmacopuncture is effective for treating mild lower back pain....

It is said that the combined effect of acupuncture, which facilitates blood and qi circulation to reduce pain, and herbal medicine, which quickly eliminates inflammation, can treat back pain even with just one or two sessions...^^

Is it really effective? I'm very curious...^^
