Hello and thank you for the reply
My symptoms sound very much like ulnar nerve entrapment. My next step is to locate a doctor in central Florida

In 2004, living in Winston-Salem NC, I had the numbness and tingling in in left pinky and ring finger. It was accompanied by a bizarre hitting the "funny bone" feeling in my elbow that was difficult to turn off at times. I don't recall it radiating as high as the shoulder//neck. Advil etc helped reduce the feeling, but it wouldn't go away, so I finally got a referral to a neurologist who discovered the entrapped ulna nerve. He referred me to an orthopedic surgeon (hand specialty vs shoulder) who did surgery around my elbow to reroute the nerve so it was no longer trapped. It was believed that my years of biking (gripping handlbars/brakes) was the most likely reason. The surgery did wonders.
However, 5 years later, the numbness & tingling returned. I lived near Johns Hopkins in Baltimore then, and the orthopedic surgeon there entered surgically and found a record-setting amount of scar tissue build up at the site, and removed the scar tissue, and after PT it was much better again.
About 5 years after that, I developed idiopathic PN, and that's how I wound up at this great site. Nobody has linked my severe axonal sensorimotor nerve PN to my left ulna nerve by the way, as it's in both lower leg & arm limbs. But I'll share that I got shingles 2 years ago, sadly when I was near rock bottom going through yet another dilemma with throat cancer treatment. Most folks get shingles on their trunk region; mine was right near the ulna nerve old surgery scar on my elbow. The shingles pain and residual effects mimicked all the entrapped ulna nerve symptoms I had back in 2004, this time radiating up to the back of arm and lower neck. I guess I'm learning that injured nerves are very vulnerable!
I guess I'm saying you sound a bit like maybe there could be ulna nerve stuff going on; my PCP in NC had referred me to a Neurologist which did take time to get in and get the nerve conduction study to confirm. But at Hopkins, it was my Orthopedic doctor who got the ball rolling, and it was a quicker route.
