The pain seems to be central to the middle knuckle or second join from the end of my left pinky.
Hello Dear,
Please be specific and mention where do you exactly feel the pain?Is there any swelling?The pain could be due to many reasons such as nerve irritation,cervical spondylosis,rheumatoid arthritis and so on.Generally arthritis is associated with stiffness,swelling and pain in other joints.Unless the symptoms become specific the diagnosis cannot be confirmed.If the symptoms worsen you should consult a orthopedic doctor.
