it's not unusual to have a period of time, even a year or more, where people can feel the ulnar nerve 'flick' or 'snap/click' around the elbow joint (medial humeral epicondyle). Perhaps most typically it relates to increased neural tension or soft tissue thickening in the area. Don't read too much into google searches that will discuss surgical interventions for ulnar nerve subluxations or removal of synovial plica's (folds of skin essentially). I may be due to the way you repetitively rest the elbow or forearm on a table e.g. the edge of the desk when working at a computer. The symptom is not really the thing to work on directly as it is more likely a cause/effect situation. See if you can identify a repetitive task that might have lead to this and then we can discuss how to approach that.
You can of course create some subluxations with repetitive exercise e.g. weight lifting with arms movements in non-functional motions e.g. chins, lateral pulldowns behind the neck, even some types of dips. In general any full range barbell movement is non functional as the forearm rotates during the normal flexion and extension of the elbow and a barbell prevents that happening.
The paid consultations on the forum are essentially that, a consultation to help to assesses what might be the issue and point in a direction / treatment approach. They are not single question and answer but they also are not an ongoing treatment session. This is mostly as we cannot assess the people who post in person and so offer a professional opinion which most often is a way to followup with some new ideas with the treating practitioner.
Do let me know if any of the above might stimulate some thoughts on your end as to what might be happening. It is now Christmas eve so we will be trying not to work over the next 3-4 days.
Best regards and Merry Christmas
