Numbness and pain in the little and ring finger which may extend up the outer side of the forearm.
I went to You Tube and tried some of the suggestions. Went to physio for my back last week and buddy says he saw the cubital vieos and said the stretching and exercises seldom help. The damage has been done. But, the exercise glove the vids are trying to promote is making someone a lot of coin.
However, on a health website, I read that one can stop further damage and 80% of peeps get some relief by keping the elbow from bending during sleep and work tasks. This can be accomplished at night by wearing a splint or by wrapping the arm in a pig blanket or by tying the wrist to ones night clothes. In about a month, this usually can be discontinued as the pattern for curling one's arm is negated or lessened. I tried sleepng in sweat pants and putting my hand in a pocket... works great until I fall asleep. When I wake up, my elbow is fully bent and the numbness is worse.
I went on a quest for a splint. Nope. I figured the pig blanket might cause a circulation problem. So, I tried sommat. I folded up a large hand towel, placed it in the crook of my arm and wrapped it with Elastoplast (a "stretchy" wrap) to hold the towel in place.
Works a treat. My elbow can't bend over 90 degrees. I am gonna try to wear it 24h/7.
