it sucks not knowing what's wrong with my fingers, for the past 3 days I haven't been able to use my fingers as much because I get pain in them. they feel so swollen. it's gotten to the point where I can't open a jar or a bag of chips, or even my baby's bottles. It comes and goes. But when I really use my fingers alot I can feel the pain inside. I'm really scared to find out I have arthritis on my hands at the age of 24. The sad part is that idk if it's from my mom's side of the family, she wouldn't know either, because she was adopted as a baby. She never met her real family. But I do know it doesn't come from my dad's side.

I'll be making an appointment to see what's going on, but I'm just really scared.
