We : We sometimes see hand numbness and swelling with compression of the nerves as they come down through the shoulder under the pectoralis muscle. If the mri's are normal ms is not a consideration.If the ncv shows no nerve slowing at the wrist ask your doctor to feel for tight knots in the pectoralis minor muscle or just above the collar bone. This is treated with stretching exercises and is often seen with poor posture. It is most common in women with large breasts and in people who spend the day hunched over a computer keyboard.

Some of the options: Cervical radiculopathy, transverse myelopathy, ulnar / radial / median nerve impingement (incl carpal tunnel syndome), brachial plexopathy, peripheral neuropathy (there are many causes), and vascular disorders, such as calciphylaxis. I agree that carpal tunnel syndrome is #1 - and should be a place to start. A normal brain MRI does help put MS aside.
