Hello, Your question can be better answered by a neurologist who would do a complete neurological examination (both motor and sensory) examination of the affected to the arm. This will allow better localization of where these sensations are coming from and whether or not the diagnosis of TENNIS ELBOW is truly the ONLY diagnosis you have. If there is some other level of nerve entrapment going on that may be higher up in the cervical spine, etc. then, a simple antecubital release procedure MAY in fact, NOT fully resolve issues. Have you had either an EMG or a NERVE CONDUCTION STUDY? I would usually do these studies to identify potential tandem lesions so that I can be sure that the patient s surgery will truly be what is needed for full relief. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Dariush Saghafi, Neurologist
