Stubbornness vs laziness

Is stubbornness just another word for lazy?  Over the past couple of years I have learned that I can be a really stubborn person, but I wouldn’t classify myself as lazy.  But the more I started to think about it the more I began to draw some similarities between the two.  Is being stubborn just another way of saying that I am too lazy to try another option?  Often times when I get aches and pains or headaches people say to take an ibuprofen but I almost always decline and just tough it out.  I have began to believe that that is just me being a bit stubborn and deciding to ride out the pain.  But is it really just me being to lazy to take a few pills??  There are many other examples but this one caught my attention today and I have thinking about it ever sense.
