Ulnar neuropathy: Ulnar nerve (nerve running on the inside of the forearm) entrapment appears likely, with a common site being at the elbow level, with wrist being common as well and among others. When affecting function, an assessment consisting of a focused exam and detailed history is needed, ideally with your GP, so that it can be addressed properly.
