### Patient: Doctor, I have been experiencing pain in my hand and finger, and it looks like the skin on my hand or arm is infected. I also have swelling in my hand or finger, can you tell me what's wrong?
### Doctor: Based on your symptoms, it appears that you have trigger finger, a condition where your finger gets stuck in a bent position and then pops straight. It can also cause pain, swelling, and inflammation in the affected finger. The infection on the skin could be due to scratching or rubbing the affected finger or hand.
