Question:I injured the ulnar nerve from a bad wrist injury. Tests now show I've got a blood clot in the artery that runs next to the ulnar nerve. Are the feelings of numbness and weakness in my hand from problems with the nerve or the blood clot?
In rare cases, the ulnar artery that travels right beside the ulnar nerve may be damaged and form a blood clot. The symptoms caused by the clot mimic problems of Guyon's canal syndrome (pinching of the ulnar nerve in the wrist). The clot is believed to shut off the blood supply to the nerve, which in turn causes symptoms.
