Hi Debm,
I too have felt a crushing full body feeling since diagnosis 10+ years. It feels kind of like the witch of the east in wizard of oz. It is a deep smashing of my bones. I feel it in my hands, face, shoulders, legs, arms.. It is non specific and throughout my body.
It stinks to have pain that does not fit the stereotypical MS textbook descriptions. Our nerves are damaged and this is how the signals come in now. Many times I have been evaluated by MS healthcare providers and been told what I am or am not feeling. Take it from a true MS expert, one who feels like you, that we are not faking it or confused by other conditions. I validate your experience and I understand your pain. Hang in there.
