answered question 12/10/2008 Recently I Had A Boil Under My Arm (pit). Walk-in Clinic Doc Put Me On Antibiotics And It Pretty Much Went Away But Now There's A Cord Or String Like Thing There In My Armpit. What Could It Be? Sounds like you need to see you PCP. Although you were given an antibiotic, most boils are usually lanced to let the infection drain out. Boils are also contagious and you made get it again in the same area or some other area.
