Where, exactly do you have pain? The tip of your elbow (the point of your elbow) is the olecranon. That's the "end" of the ulna (or, rather the "beginning" but that's semantics). It would be unusual if that's what truly hurts.
There's also a bony prominence about two fingerbreadths from the olecranon towards the "x." That's the medial epicondyle, a part of the humerus. Forearm flexor tendon muscles originate from that, and that's what hurts in medial epicondylitis.
Also possible (because it's in that area), but not common, is a partial tear of the biceps tendon. Yes, you can feel the main tendon in the soft fleshy "front" of the elbow (the antecubital fossa, where you get blood drawn). But there are also strands--like a sheet--of connective tissue that anchors the tendon down to the medial side of the elbow; it's called the lacertus fibrosis. That can be torn (or partially torn), giving pain in that area, too. If you have a lot of pain when you rotate your arm to turn your palm up (like in turning a screwdriver), then that might be the culprit. Usually, though, you'd have noticed some bruising in the area. And, usually, biceps tears are more likely in people in their 40s and 50s.
