Is this happening because my pants are too tight?

So I need a little help. The past couple days, my clitoris and my vulva have been a little tender, but I haven't touched it at all except when washing in the shower and when wiping. Could it be my pants are too tight in the crotch or something? Or could it be something more serious? Any advice or speculations would be helpful so I can ask my doc if some people think it's serious.
