Hi, I had surgery a little over a month ago. Had a herniated disk removed and fusion on C 6, 7. The tingling and numbness I previously had in my arm was pretty much gone, and the pain was getting a little better. Last night I took a fall, not super hard, but I did go down on my knee on the cement. Today, I am really hurting, especially in between my shoulder blades, and the numbness and tingling I had in my arm is back. My question is, how difficult is it to re-injure yourself when something like this happens? I know the Dr. said it'd take a while for the nerves in the arm to get better and that in between shoulder blade pain is normal, but I'm a little scared.
