Heart patient with a boil and running a fever?

Boil causing fever: You hate to think that a simple boil can become more complicated but certainly it can. This depends on the type of germ causing the infection & the person (you) dealing with the infection. Hopefully u can get some help, because in ur case I'm worried ur body is struggling to control this disease. Best to call your primary doc now & ask what to do. You may need antibiotics or even a quick drainage.
