In the last 6 months I have noticed random swelling in my knuckles and in between knuckles. Before the swelling starts I will get a weird bump under the skin that makes the skin red in that spot. Lightly painful to touch. After about a day of the bump, the entire finger will swell up. I can't even bend that finger until the swelling randomly goes away on its own about two days later. This happens randomly to all fingers, sometimes multiple fingers at a time. I do have ulcerative colitis which I know cause larger joint like the shoulders and knees to become sore. I am 21 years old. I don't smoke, drink or do drugs or even any over the counter medicine. I eat healthy and am in relatively good shape.
Does anyone else have this or know what it may be?
