I am 14 and have come home from a day out (it was very cold and i had no gloves on) to discover that my index finger on my right hand and my little finger on my left has swelled in the middle where the joint is. When i bend them they feel tight and it hurts a little. It feels like there is liquid trapped there. Does anyone know what this is and what might of caused it? im getting worried that it might be arthritis of something! Thanks(:
