Hi My Name Is Hillary And Back In June Of

Hi my name is Hillary and back in June of this year I was playing in wet grass and was barefoot and slipped and fell on my right leg and felt a pop, I hurt my upper leg, and barely sprained my ankle and now I think that I injured my Achilles' tendon because I have issues trying to flex my foot, and my ankle is still swollen. I went to PT for awhile and just am asking if I should get an MRI on my tendon to see if it ruptured? It hurts me now more then ever, and just need some help

Thanks
