Can Fascia Unwind Or Tear, And Could My Sensation Of Something Pulling And Separating Under The Skin Be Explained By This?

Can Fascia unwind? I felt a tear in the pinky of my left hand and I feel IT pull, until it separates from me and is gone. I believe its just floating under my skin. I ve had x-ray and cat. Told its in my head, but I feel a MRI is needed. But can t get a Dr to sign for one. Advice?
