First off, I'm a 14 year old girl and I don't have any kind of condition that I know of, but I think I might have a symptom of asthma. I haven't been diagnosed. My knuckles and the joints above them (idk what they're called) are like this bruise- blue color. I don't think they're actually bruised because they don't hurt when I press down. I washed my hands so it's not dirt. What should I do? Is it serious? Should I tell my parents?
