Hi, I am a sixteen y/o male and I have swelling in three of my knuckles (two on the right hand, one on the left). There is swelling further up one of the fingers but it seems to be concentrated around the knuckle. It is red, not painful but at times itchy/tingly. It has appeared before, possibly two or three times, never causing any pain but it seems to swell and itch for around a week and then go back to normal. I have had it probably twice in the last two months but it is winter, and very cold, i m not sure if that has anything to do with it.
