I had a very bad episode of neck pain in December. The pain flowed into my left arm, and my left arm became restless (internal ibrations, twitching and even pulse/heart beat) and weakness. After a few physiotherapy sessions, the left arm symptoms and pain died down, but have returned.
Everyone I talk to, even people who had cervical herniations, said yes to pain and weakness - but not twitching and heart beat (pulse). They also ALL had numbness and pins & needles.
I do not have any numbness or pins & needles. They all told me it could be how the nerve is compressed. I looked at diagrams on the internet and see that usually when the herniation happens, it compresses the top sensory nerve before it compresses the bottom/back motor nerve - unless I am looking at that the wrong way.
I can't find any information online on if a herniation can cause only my symptoms without numbness and tingling, so I thought I would ask on here for your experiences and thoughts.
Note - no doctor has yet prescribed any kind of diagnostic test like an MRI. If the symptoms don't get better or keep returning by my follow-up appointment in April, then he said he will send me for an MRI.
