<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 70 year old white female with a soft firm pink bump size of a small green pea that suddenly erupted 4 months ago on top of my knuckle second knuckle back from the fingernail on left hand, middle finger. It is not causing pain or restriction of movement. Another 2nd one of same description is starting up now , but still very smaller, on the next finger pointing finger in the same location as of the first bump. Is this arthritis? Thankyou, Carol. YYYYYY  <response>: HI, Dear,Carol MDM. Very Good NOON from India. Thanks for your query. I understand your concerns. I studied your query in depth.-I would advise you not to worry still. In my opinion the painful lump in the 2nd and 3rd middle-knuckles is -mostly Rheumatoid Arthritis- or could be due to digital mucous cysts of the small joints common at this age? Or Granuloma annular cell granulomas around small joints.-Treatment-would be -Consult an ER Physician Rheumatologist doctor-who treat it as per the cause of the digital lumps.-Hope this reliefs your worry-some query. Welcome for any more queries in time to come. Have a Good Day.
