Brain and Spine Problems

Three weeks ago my left arm went completely numb and I was having stabbing pains. I have also been having a lot of headaches. So they did a MRI of my brain and it came back with 6mm descending cerebellar tonsils, suggestive cerebellar tonsillar ectopia and a 15mm right maxillary sinus mucous retention cyst. What does all that mean?

I'm having this sensation where the left side of my head/face/forehead, the left side of my shoulder and arm and down to my left chest (close to the heart) and also below the chest (close to my left rib cage) is feeling so tight, like someone is pressing something towards it. I also have hard time breathing, this is so hard to deal with, an answer would be nice. Bye, thanks.
