That's a description of a deterioration of part of the spine in your neck. The correct
place to get more detailed information, with some authority behind it, is from the
Doctor Who ordered the scan, or the radiologist who evaluated it, or whoever else
told you that you have the protrusion.
Personally, I've had five scans of that section of my own personal neck, and two
surgical operations, 12 years apart, to fix things in that neighborhood. And from
my own personal experience, I can tell you three more things:
#1). If you do have surgery to correct it, then for about a week after that, you'll
wish you hadn't.
#2). Starting about the second week, you'll be living a new life. That strange
new feeling you notice will be the absence of pain that you didn't even know
you had before.
#3). The internet is no place to be looking for information. Explaining it to you
is just as much the doctor's job as fixing it is.
5 mm = 5/1 mm
5 mm x 5 mm = 25 mm2
5 mm
5 mm...
There are 1000 microns in a mm. There are 5000 microns in 5 mm
92.5 mm is larger than 5 mm
1 inch = 25.4 mm (rounded)5/16 inch = (5/16) x (25.4) = 7.9375 mm (rounded)
5 of course
5 mm?
29 in. = 736.6 mm 21 in. = 533.4 mm 5 in. = 127 mm
1 in = 25.4 mm, so (5/1000 in)*(25.4 mm/in) = 0.127 mm
1 cm = 10 mm → 5/10 cm = 5/10 × 10 mm = 5 mm
