Suggest Treatment For Joint Pain

I'm 21 years old and pretty healthy. I weigh 140 lbs and am 5' 4". I have allergies and anxiety issues but the main issue lately is my joint pain. Arthritis runs in my family but I feel like I'm too young to have it already. It has recently gotten worse. It changes with the weather and is at it's height later in the evening, sometimes making it hard to sleep. At first it was just my knees, but I was a catcher for about 6 years and thought that was just the effects on my knees. It has moved to just about every joint now, all the way through my fingers, toes, elbows, sholders.... etc. Can it be arthritis at 21?
