The conversation between human and AI assistant.
[|Human|] The tip of my middle finger on the left hand is painful, swollen, red, and throbbing. Yesterday it was more red and the entire finger got red but that went away rather quickly. Today, the tip of the finger is less red but still painful, swollen, throbbing and tingly. What is the problem and what can I do about it?
[|AI|]  Hello, The redness and swelling can be due to some injury which must have happened without the knowledge. If no injury happened than It's nothing to worry. Because certain times the body has its reaction with the vascular supply, and it heals on its own. Doing hot water fermentation and finger movements in the water will be beneficial. Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.
