I get pains in my rib cage that feel like it is being squeezed, people with MS call these "hugs", and it is a very good description. I have Baclofen for these and to reduce the number of muscle spasms I get. I also have symptoms of pudendal neuropathy, so yes it can progress to the trunk. The pain, pins and needles, numbness, and reduced sensation have progressed for me to hip level and upper arms. If I turn the shower unbearably hot I cannot feel it below my lower back.
I have hereditary neuropathy (CMT) and it is progressive.
