<s>[INST] Husband has infection on finger. . .  probably an infected hang nail.   White cuticle plus very swollen.  Started about Tuesday.   Last night went to doc and got antibiotics.   4 doses so far.  This afternoon he noticed a red line coming from the finger and it is half way up his hand. . .   Want him to go to emergency room.  He doesnt think so.  Your recommendation? [/INST] Hellowelcome to Chat Doctor.I appreciate your concern. From your history it looks like that the infected finger nail gave rise to a cellulitis of the hand.I need to know that your husband is diabetic or not??it is more common and more aggressive in diabetics. Yes you need to take him to emergency. Prompt diagnosis and treatment is necessary here to prevent further complications. Hope this is helpful to you. Post other queries, and we shall be happy to help you.regards. </s>
