Feeling refreshed after arm pain treatment at Dahong Oriental Medical Clinic in Ansan

My left arm has been feeling extremely heavy for a few days now. It's been hurting so much that I can't even lift my arm.
I tried applying patches over and over again, but it just got worse and worse. It was so painful and numb that I couldn't even lift a spoon... I was so scared that I imagined all sorts of things, like a herniated disc in my neck.
I finally took the time out of my lunch break to go to Dahong Oriental Medical Clinic.
The teacher turned my arm around and said that fortunately it wasn't a bone problem, but rather a severe strain on my muscles and ligaments.
I got a few acupuncture needles and received electrical physical therapy (the kind where they put on something like a cupping device and it tingles!). Every time the electricity came on, my arm muscles would twitch and dance on their own, which felt strange... but after it was over, I felt refreshed, as if my tense muscles had loosened up!
After getting treatment, I was amazed to see my arm, which had not been able to go up, go up again ^ ^
I still feel some pain, but I feel much better.
