I suspect medial epicondylitis, too. I have personal experience with the issue. As you are likely aware this can be ligamentous (ulnar collateral ligament), but in weightlifters I believe is usually due to flexor carpi ulnaris or radialis tendonitis. The pain occurs with extension of the elbow, but may worsen with isometric resistance of ADduction or ABduction. The differential diagnosis (for adults) includes stress fracture and osteoarthritis.

Unfortunately, conservative therapy is rest for up to six months in bad situations if you only have tenderness during movement. This time is dependent on the person, but I would recommend a minimum of 3-4 weeks with no weight (ROM only) to allow for some remodeling. Then slowly introduce weights. If you notice discomfort then stop for the day, and return to the exercise again at your next scheduled workout. I personally was on the six-month side because I did not stop like you did until the pain was at rest too (being a doctor I should know better…). Tenderness at rest will warrant Xray first, medication second, and MRI third for most recreational athletes.
