My father said that both of his hands kept hurting alternately, so I looked into it and found a nearby rheumatology specialty hospital. I went there because I thought it was rheumatoid arthritis, and they did an ultrasound, blood test, and other tests. They said it was rheumatoid arthritis, so I got a shot and started taking medication. The pain was so bad that I couldn't make a fist and couldn't sleep, but after the treatment, the pain gradually disappeared, and now I'm much older. The medication is still ongoing, and I decided to continue the treatment because they said that the symptoms could come back if I stopped taking the medication, and I'm currently completely pain-free.
