Your symptoms sound similar to a potential serious side effect my gynecologist warned me about when I started
Nuvaring. As I recall, the painful lump is a blood clot traveling up your
leg so it can give you that aneurysm you always wanted but could never afford. Seriously, her advice was something along the lines of GTFO ER ASAP (I'm out of acronyms), unless you want an aneurysm for some reason. I have heard that it's a relatively quick, painless, and surprising way to die.
