<s>[INST] My right index finger has swollew up just before my Knuckle.  Sharp pain on the finger and I have a tingling numbess feeling all the way up to my shoulder.  there is a red bump on the top that has formed but I did not jam it or remember being bit by anything.  at first I thought it was an ingrown hair [/INST] HiT hanks for posting in ChatDoctorThat sounds like an infection. Other causes of bump on finger will not have inflammatory properties. What you describe sounds inflammatory and only an infection like an abscess will give you that presentation. I will suggest you see a Doctor for examination. You may take pain/anti-inflammatory medications like ibuprofen and see your Doctor to judge the need for antibiotics. Hope my answer will help you Best regards </s>
