    I have little tiny round clear looking bumps on my knuckles on both the hands. I wonder if they are cysts and can they be removed?

    I accidentally cut my index finger knuckle two months ago and it is still swollen and it is paining. I had got the x-ray done and it is not broken. I am taking antibiotics and have been soaking finger in warm water with Epsom salt. The Ffnger is more swollen when I wake up and swelling goes down during the day.
