Osbourne also suffered embarrassment while sitting patiently until the doctor was ready to examine her as she unwittingly sat under a medical poster of a penis in the waiting room.
In another Instagram post, she wrote: "When you are sat in the doctors office w/ a diagram of a penis above your head & no one tells you!!!!!! (sic)"
This is not the first time, the 30-year-old star has been bitten by a spider.
Last year, Osbourne had to get an injection in her jaw after a creepy crawly used its fangs on her face.
She revealed on Twitter at the time: "I have no words to express how much a spider bite to the face hurts. Plus a large injection in my jaw ... today sucks b***s! (sic)"
