I have a lump on my elbow next to the elbow bone and i have an uncomfortable pain in my forearm and tricep, it doesn't look like a zit or bug bite ?

Likely bursitis: You should seek evaluation by an orthopaedic surgeon or physician focusing on musculoskeletal injuries. The image shows a typical appearance of olecranon bursitis- a common condition that usually resolves with rest, ice, anti-inflammatory medications (nsaids), and brief immobilization. Aspiration is frowned upon due to increased risk of infection, but is occasionally indicated.
